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, our 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.

Hose Clamps
Hose clamps ARE NOT included with the purchase of this, nor any other silicone product that we offer, but they can be included at an additional charge upon request. Please contact us directly for pricing and availability of our highest quality stainless steel clamps.

Please be aware that these hoses were patterned from right hand drive vehicles. Whilst we believe these to be correct for left hand drive vehicles we suggest that you visually check their suitability, as replacement items, with those fitted to your own vehicle, before attempting installation.
