The new 3.0 TFSI turbocharged engine in the current B9 S4 will really benefit from our TriFoam™ High Flow Intake Filter. Using the exact same filter material as our intake systems, it’s a simple-fit replacement for your factory paper filter. Expect a worthwhile boost to engine efficiency as a perfect complement to either a standard engine or those running uprated power.
OEM-standards of design, quality, materials and construction, hand-made in the UK. Fits like a factory part; lasts like a factory part.
Allow your 3.0 TFSI engine to breathe better and operate more efficiently, improve the engine’s airflow and power and fuel economy gains will follow.
Our design uses a non-sealed end which adds to the already larger surface area to allow significantly better flow.
By removing the inevitable restrictions that the standard paper panel filter gives, this Performance Filter allows a worthwhile increase in airflow through to the turbo.
The result? More mid-range power and improved economy, without wrecking your warranty.
Testing has shown an additional 20NM of torque on a standard 3.0 TSI engine. A small but worthwhile difference to the feeling of mid-range power.
