The highest-performing, race-bred cold-air induction system for the current B9 Audi S4 & S5

LET YOUR ENGINE BREATHE.

SIMPLY 

THE BEST. 

WHAT'S SO

SPECIAL?

Our latest Cold-Air Intake System kit for the current 'B9' Audi S4 and S5 enables cold, dense air from outside the engine bay to reach the fuel metering unit more efficiently for great power gains.

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 

The intake uses a clever design which retains the original Audi lower box of the intake, adding in a replacement lid, TriFoam™ filter and front intake scoop

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

It's not just about performance; the beautiful carbon weave of the intake will enhance your engine bay every time you lift the bonnet!

GIANT TRIFOAM® FILTER

Our unique Trifoam® filter construction is 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

Lots of cold, fresh air plus efficient filtration and huge filter surface area means power and torque gains support higher power remaps.

PRECISION ENGINEERED FOR PERFECT PERFORMANCE

Cold-air intake scoop ensures a constant feed of the cold fresh air that the engine needs 

Trifoam™ filter construction, a triple-layer laminate of open-cell polyurethane foam, gives an exceptionally high level of filtration

Beautiful matte-finish carbon fibre is strong, lightweight with excellent heat transfer characteristics

A formed intake box specifically for the Audi B9 retains original lower box with carbon lid
