Foamfirst 

ITG were probably the first company to manufacture a truly durable, 

high performance foam-based production air filter. 

Why foam? Because, compared to paper or other filter technologies, 

reticulated polyurethane foam achieves optimum performance against three 

key criteria: 

1. Maximum Air Flow – the ability to allow air to pass 

through without causing a large drop in pressure. 

2. Cleaning Efficiency – the ability of the filter to remove 

dust and contaminents from the airflow. 

3. Dust Load-up Tolerance – the capability to absorb 

a large amount of dust before cleaning or replacement is 

required. 

With our unique TriFoam TM System, which uses various 

thicknesses of finer or coarser foams, these factors can be 

varied for different applications. 

TriFoam TM gives us the flexibility to produce air filters to 

exact customer specifications. We can tailor the dust 

filtering capability to well below 5 microns for roller barrel 

throttles, superchargers and 

cabin filters. 


Advanced technologies 

Compared to other filter media, ITG foam filters offer many 

additional advantages, including a significant reduction in 

weight while providing more power for longer. 

What’s more, because we use the very latest adhesive 

technology to bond the foam layers, ITG filter assemblies 

are resistant to water, fumes, oils and fuels. 

With our pedigree, you can be sure of a high quality 

product, combined with a very quick turnaround time and 

competitive pricing. These qualities have kept ITG at the 

forefront of technology and helped motorsport teams win 

countless world championships with our air filters.

Superior Filtration 

Results from tests performed at the Motor Industry 

Research Association (MIRA) show that against leading 

paper element and cotton gauze filters, ITG foam filters 

outperform all competitors for low pressure drop (mbar) 

versus dust loading (grams). Typically, ITG air filters can 

hold 5 times the quantity of dust than an equivalent paper 

or cotton gauze air filter, giving better airflow over a much 

longer time. Our unique TriFoam TM system, with 3 layers of 

differing porosity foams, combined with dust retaining oil, 

give a high level of filtration to protect the engine from 

wear due to dust inhalation. If you want to go faster for 

longer, choose ITG airfilters. 

Look at the figures in the graph to see just how an ITG filter 

out performs the best cotton or paper filters. 

Durable rubber seal 

Engineered to fit tightly against the foam sleeve, 

this seal creates a dust-free sealing solution. 

Stainless steel wire mesh 

To avoid erosion, we only use the highest quality 

stainless steel.

More Power for longer 

Pleated paper, synthetic polyester fibre and cotton gauze 

airfilters give good flow rates from new at the expense of 

clogging up quickly, causing a gradual loss of power over 

time. ITG foam air filters can hold the same performance 

levels from new with 5 times the quantity of dust than 

other media. This means more power for longer and less 

maintenance. 

Longer Life 

All ITG air filters are washable and reusable, and can last 

up to 15 years when oiled and maintained in line with 

instructions. Better for you – better for the environment.

Direct replacement filters 

Over the years, ITG have created the lightest, most capable filters for all 

fields of motorsport, from Formula 1 to the World Rally Championship. 

The same design skills, advanced technology and attention to detail are 

also used to produce our Profilter range of high grade replacement filters 

for both road and competition use. 

With such a pedigree, you can be sure of a quality product 

with a superior performance – and a highly competitive 

price. Consider these benefits: 

Superior filtration 

Our unique TriFoam TM system with three layers of foam 

combined with the arresting stickiness of the dust retaining 

oil gives a high level of filtration to protect the engine from 

all contaminants brought in by the air. 


Better economy 

You can be assured of better fuel economy due to the larger 

volume and more consistent flow of air into your engine. 

As a result, smaller throttle openings will achieve the same 

performance. 

More power 

Performance is unaffected by very large quantities of dirt 

arrested in the filter and, long after ordinary filters have 

blocked up and reduced the engine power, loss of pressure 

in the Profilter airflow will be exceptionally low. 

Longer life 

In normal road use, a Profilter will last at least 5 times as 

long as the equivalent standard filter. Waste is reduced so 

Profilter helps the environment as well as the engine. 

Cleaning 

All our Profilter range can be washed and re-oiled with our 

filter maintenance kit.

The famous red-band TM 

filters for road and race 

These versatile filters are easily recognisable by their twin bright red 

bands around the top and bottom. They should not be confused with the 

many inferior types of foam air filter. 

These bands are the visible part of two fibre-reinforced nylon injection 

mouldings which form the structure on which our unique TriFoam TM filter 

system is bonded. 

The two outer layers of foam provide optimum filtration and 

load-up capacity while the inner layer is made of special 

self-extinguishing filter foam. Together, they give the best 

combination for air flow, engine protection and safety. 

All standard baseplates for the Megaflow range are made 

from bright red powder coated steel. 

Fitting advice 

Selection of the filter element depends on the amount of 

room available. 

ITG recommend fitting the tallest element possible, though 

a gap of 1/2” (13mm) average must be left over the top of 

the filter for air to circulate. 

If using ram pipes, there must be an absolute minimum gap 

of 3/4” (19mm) or preferably 1 1/4” (32mm) between the end 

of the pipe and the underside 

of the top of the filter. 

Please note: 

All types of Megaflow filter are available as either a flat or domed (sausage) shape. 

Baseplates are also available in aluminium.

space between air horns 

and front panel.

Fitting instructions 

Fitting a filter is very straight forward. The baseplates are 

supplied with bolt and spacer kits when required. The filters 

clip onto the baseplates, and are secured by one or more 

simple 1/4 turn fasteners. In many cases an improved seal 

between carburettor and baseplate can be achieved by 

applying a thin smear of silicon grease. 

The Megaflow range of air filters is normally supplied 

unoiled or 'dry', and they need to be oiled prior to use. 

For very light dusty conditions or track use, we recommend 

our JDR-1 oil. For very dusty conditions – rallying, grass 

track etc., we recommend our JDR-2 oil. Both products are 

available separately or in a maintenance kit with filter 

cleaning fluid. Alternatively, for a very small charge, we can 

pre-oil the filter for you at the factory when ordering. 

For particularly arduous conditions, oversocks are available 

for the twin red band versions of the Megaflow range. 

Again, they too need to 

be oiled with JDR-2 

before use. 

Important: 

All filters must be oiled prior to use 

Carburettor adjustment 


Whenever an ITG filter replaces an original equipment inlet 

system, the fuel metering systems on an engine may need 

adjustment to compensate for the change in air flow 

capacity. The following is a guide, but the full engine range 

should be checked on a rolling road. 

For Weber, and similar types of carburettor, try the following: 

Single choke 

Increase main jet 5-10 points 

Reduce air corrector 10-15 points 

Dual choke 

Increase secondary main jet 5-10 points 

Reduce secondary air corrector 10-15 points 

Reduce primary air corrector 5-10 points 

Twin choke 

Increase main jets 5-10 points 

Reduce air correctors 10-15 points 

For SU and other types using a metering needle, it is 

necessary to reduce the diameter of the needle near the 

narrower end. There is a large selection of SU needles 

available and we can help with recommendations for trial. 

For Strombergs, Ford VV and GM Varajet carbs, information 

and needle variants are more limited. 

Fires, fuel ‘standoff’ and ‘blowback’ 

The main causes of ‘standoff’ and ‘blowback’ are wild 

camshafts, poor cam timing and poor ignition timing, but 

poor fuel metering also has an effect. If a heavy ‘standoff’ 

of fuel is occurring then some fuel will accumulate on the 

air filter. If a ‘blowback’ occurs, this fuel and fuel in the 

carburettor can be ignited. Although the filter materials 

used are fire retardant, with the inner layer of foam selfextinguishing, 

a fire fed by fuel can seriously damage the 

filter and a severe under-bonnet fire may not be contained 

by the filter.

The multi-layer foam filter materials are similar to those in the 

MEGAFLOW ranges and are therefore fire-retardant. The filter is 

rated for up to 260 or 350 bhp, so it has plenty of capacity 

in reserve. 

It can also be used with any of the DGAR, DGAS or DGR ranges 

of carburettors. 

The standard JC10 is now available with an increased overall 

height (JC10R) for greater dust holding capacity. 

These simple, light, but robust air filters come complete with 

baseplate, brackets and clips for a quick-release attachment to 

the Weber DGV or DGAV carburettors used in the F2 Stock Car 

formula.

1. Where no filter element is given, please check size on installation. 

2. 40 DCOE's may require 2JC20 type gasket to locate and secure auxiliary venturis. 

3. Dellorto 36 DRLA's have only two fixing studs on each carburettor. 

4. Solex DIS, BISA, etc may have to remove studs. 

5. Use JC20/65 if possible. 

6. Please check for adequate space on Lotus. 

7. Only fits Elan with bonnet bulge. 

8. Cars with air conditioning require shorter filter elements. 

9. Renault cars frequently have very limited bonnet clearance, please check filter height carefully. 

10. Fitting of filters on Minis depends on manifold, bonnet and bulkhead types, usually a JC20/25 will fit, 

but sometimes no filter will fit at all, or a 'slanted top' filter may be required.

Airhorns 

For many years now, ITG have produced a wide variety of full radius air 

horns, slot in ram pipes, radiused inlets and separate spinnings/machine 

flanges for customer’s own fabrication. 

On this page we have included a selection of the popular items but 

have a vast range of air horn spinnings that are not illustrated. 

If you cannot see just exactly what you need, please call us on: 

024 7630 5386. 

A full range of JRP, FR, AH and Stubbies are available 

from our stockists. Again call us on: 

024 7630 5386 for more details 

and a specification sheet. 


When space will allow, air horns, either 

full radius bolt on (top), slot in (middle), or 

just radiused ‘stubby’ castings (bottom) 

can be fitted under the air filter and are a 

simple way to increase your engine’s 

performance.


Ram Pipes 

The JRP range of ram pipes are designed for use on Weber 40 

and 45 DCOE style carburettors. 

37mm of the JRP ram pipe 'slots' into the carburettor. 

Please note: they will not fit Dellorto equivalent carburettors. 

The JEM range will fit Rover V8 applications.

Full Radiused Air Horns 

The FR range of bolt on air horns are designed to fit both 

side and vertical draught Weber and Dellorto carburettors 

as well as throttle body equivalent set ups with 65mm 

bolt centres. The full radius design accelerates the air 

into the inlet to improve air flow. 

The FR48/SP is for Weber 48 DCO'SP carburettors only.

Premium quality induction kits and remote air filters 

Maxogen induction systems are revolutionary kits that enable cold, dense 

air to reach the fuel metering unit more efficiently. 

These remarkable units can deliver as much as 9% more effective peak 

power at the wheels, and in some cases at 500rpm less revs in doing so. 

ITG are able to supply fully enclosed air intake systems for 

some of todays more popular cars. This range is increasing 

on a regular basis so please get in contact with us for a full 

application listing. 

ITG fully road test all prototypes to prove their durability 

and performance, and each kit is tested on the rolling road 

to fully enhance it’s capabilities for that particular car. This 

means we are able to offer power and torque graphs for 

each kit we supply. 

Most kits come with a carbon fibre housing but in some 

cases we can offer an aluminium version of the airbox. 


Each silicon hose is designed and made for each 

specific application. All aluminium parts are anodised 

and we supply stainless steel or plated 

screws, nuts and washers to fully 

enhance the appearance and 

durability of each kit.

How does the Maxogen 

airbox system work? 

Following years of experience designing induction systems 

for both rally and touring cars at world championship level, 

ITG are now making a range of purpose designed air boxes 

to form the core of a super efficient air induction system 

for any car. 

These optimised carbon fibre and aluminium housings use 

our renowned Maxogen range of air filters in varying sizes – 

so, depending on the space available when the standard air 

box has been removed, one of these air boxes will fit most 

modern road cars creating a better air flow, and 

providing increased performance. 

Improve airflow Enhance performance 

The airbox housing features a radiused induction 

trumpet feeding from a large diameter primary inlet 

ducting arranged to collect cool external air. The trumpet 

design recovers air pressure from air velocity, filling a 

plenum volume around the large surface area of the 

MAXOGEN filter. 

The radiused outlet of the MAXOGEN filter (below) connects 

to a high quality secondary duct to feed clean, high 

pressure, cool air to the engine. The complete system is 

amazingly light, typically weighing only 800 grammes, and 

yet it can handle air for up to 300bhp with ease.

Specialist performance filter systems 

ITG’s racing credentials are second to none, and our extensive capabilities 

put us in pole position to offer the best service in the business. 

We are a major supplier to all professional motorsports where the exacting 

demands of designers and engine builders are met by ITG’s painstaking 

application to detail – in both design, and assembly. 

What’s more, we never compromise with materials or with 

workmanship, and we can offer the best hand made 

products available, in the quickest time, and with the least 

amount of fuss. 

We can advise on how to best utilise the space available and 

we can manufacture filters to any size and shape, or to any 

design of air box, from modern day to historic racing cars. 

Foam is a very flexible product to work with, which means 

we can create unique one-off filters that cannot be 

manufactured anywhere else in the world. 


We are able to use different specifications of foam in multilayer 

laminates which enable us to cater for all possible 

environments. 

This means we are able to custom manufacture – not only 

a special size, but special filtration requirements as well. 

Whether it’s a simple panel filter or a special ‘sock’ to fit 

within the tight confines of an engine bay, our team of 

skilled technicians are able to produce an air filter to 

suit every need.

Racing filters 

This ultra high performance filter was originally designed for use 

on Cosworth DFV and derivatives in F3000, but it's excellent 

design has found many V8 and 4 cylinder applications. It is 

lightweight and the three button fasteners retaining the filter to 

the aluminium base are accessible from above. The filter is 

entirely fire-safe, the internal foam being self-extinguishing. 

It should be noted however, that these are pure race filters and 

we do not recommend them for normal road use. 

The JC71,a shorter version of the popular JC70 air filter, has 

been designed to give the same performance but for 

applications where space is at a premium.

F2 Stock Car filter 


This simple, light, but robust air filter comes complete with 

brackets and clips for a quick-release attachment to the 

Weber DGV or DGAV carburettors originally used in Formula 

Fords, but now very popular with the F2 Stock Car formula. 

The multi-layer foam filter materials are similar to those in 

the MEGAFLOW ranges and are therefore fire-retardant. 

The filter is rated for up to 350bhp, so it has plenty of 

capacity in reserve. 

It can also be used with any of the DGAR, DGAS or DGR 

ranges of carburettors.

Ultralight high performance air filters 

Our vast knowledge gained in the motorsport industry has allowed us 

to tackle the very precise requirements for motorcycle air filters. 

We have developed specialist laminate foams to allow correct breathing 

and appropriate dust filtration for these high revving engines. 

ITG have a comprehensive range of applications and are constantly 

seeking new applications to further develop the range and bring 

new products into the motorcycle marketplace. 

Bridging the gap between two and four wheels and 

developing filters that work is not as simple as it sounds. 

Motorcycle filters tend to have much less surface area than 

cars – requiring a high flow filter with minimal pressure 

drop, a filter that will retain the essential dust filtration 

levels, keeping your engine from premature wear and 

maintain performance. 


ITG have the experience to offer solutions for these factors 

and we work closely with motorcycle race teams to achieve 

the ultimate performance from our air filters. 

This technical understanding and customer focus 

has allowed ITG to successfully gain contracts with leading 

motorcycle companies to supply manufacturer approved 

aftermarket race and performance filters.

In one example, we looked at an original pleated paper filter 

having a weight of 224 grams. The competitor’s equivalent 

cotton gauze filter weighed 345 grams. ITG were able to 

produce a filter with higher airflow and retain the dust 

filtration requirements, but with a weight of only 84 grams. 

ITG do make the lightest performing air filters on the market! 

ITG are used to producing one off bespoke designs for 

motorcycles which have been converted from carburettor to 

fuel injection and often we can take one of our stock filter 

designs and modify it to suit the new arrangement. We also 

produce individual or dual trumpet socks to suit many of the 

old 2 stroke applications like RD500’s and also many 

V twin applications. 

The manufacturing and shaping of foam filters into obscure 

shapes is very easy compared to pleated cotton gauze or 

paper filters. This means that we can produce a filter for 

any application where there is sufficient space – with no 

specialist tooling and rapid lead times, keeping costs to a 

minimum. 

If you have a requirement for any motorcycle air filter, 

please contact us and we will be glad to assist.

All foam air filters should be oiled to provide the best filtration 

performance. The recommended oils are specifically formulated for 

foam air filters. When the oil is correctly applied, it provides a tacky 

coating over all the surfaces of the structure of the foam filter. As 

dust particles pass into the filter, they collide with the foam 

structure and are then retained in the oil coating. The oil coating 

also flows around the dust particles to continue to present a tacky 

surface for further dust particles. 

If foam air filters are used in a ‘dry’ or non-oiled state, they still 

provide filtration of larger dust particles, and they will also retain 

most smaller dust particles due to an electrostatic effect. 

Electrostatic dust retention is much less reliable than oil retention, 

so if a filter is used without oil, it is very important to monitor 

whether any dust is passing through the filter, and to clean the filter 

frequently. Some dust, which can potentially damage the engine, 

may pass through a filter used in dry condition. 

ITG will not provide any warranty when a filter is used in dry 

condition, or has not been maintained according to instructions. 

There is a popular misconception that oil from air filters can become 

detached from the filter, pass through the air, and contaminate a 

MAF unit (mass air flow meter). Oils designed specifically for foam 

air filters are too viscous to become airborne and migrate onto MAF 

units. All pre-oiled ITG Profilters have the correct amount of oil 

applied and will not cause any issues with MAF units. 

Under no circumstances use cotton gauze filter oil, engine 

oil or any other oil not specifically manufactured for foam 

air filters.
