Racingline VWR12A1S1 Cold-Air Intake
The highest-performing, race-bred cold-air intake for the Audi S1.
WHAT’S SO SPECIAL?
- One of our most popular products is our Cold-Air Intake System kit, enabling cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently for the Audi S1.
- Our High-Flow TriFoam™ triple-layer construction is simply the best filtration material on the market, and is the key to the power gains achieved.
- Each filter is handmade in the UK.
- Developed for use in our Volkswagen Racing cars, the system delivers really impressive airflow gains – as much as 9% higher at peak power than that of the original intake system.
- By reducing turbo spool by up to 500rpm in some cases through the enhanced efficiency of the system, lightning fast turbo response is guaranteed. In our experience, no other intake kit gives higher gains.

TRIFOAM® FILTER UNIT VWR12A1S1
Faster, for longer
The highest airflow of all filter types, for the best possible power for more of the time. As a high performance part, regular maintenance is essential to keep it at its very best.
PLEATED COTTON FILTER VWR12A1S1C
Fit and forget
A robust ‘fit and forget’ filter that will last for years. It gives great initial power output but doesn’t have the ultimate dust-loading capacity of Trifoam®.
