The peaknumbers at WOT are pretty impressive, but what may not be as apparent is that thepercentage of increase in air flow is greatest right off idle, between 5° and 25°. The increasein this area is as high as 23%, which translates into better off-idle response.OEM Cross ReferenceAppendix & Index3-70NOTESAir cleaner and manifold must be ordered seperately.
