What’s so special?
One of our most popular products is the VWR Cold-Air Intake System kit, enabling cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently for 2.0 TDI engined Golf mk5, Audi A3 8P and Leon II.
- Our giant high-flow filter 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 TDI Volkswagen Racing cars, the system delivers really impressive airflow gains – as much as 9% higher at peak power than 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.
GIANT FILTER
Your choice of our unique Trifoam® or Pleated Cotton filter construction, hand-made in the UK for the perfect filtration and minimum restriction.
SOUND QUALITY
You’ll hear the rich induction noise from this race-bred intake as soon as you accelerate hard. However, as a fully-enclosed intake, volume levels are well-contained.
POWER GAINS
Efficient filtration and huge filter surface area means power and torque gains support higher power remaps.

PLEATED COTTON FILTER
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®.
