After encountering the collapse of the OEM intake air hose on the Audi S3 (210 & 225) and TT 225 engines (this typically occurs around 5000rpm) that had been re-chipped, Forge's development team set about the manufacture of a hose with re-inforced walls to remedy the problem. The replacement silicone hose was also aerodynamically improved internally to maximise power by removing the existing restrictions.
