RacingLine Performance Panel Filter – Audi S4

Our High-Flow Intake Filter for the new B9-platform Audi S4 and S5 replaces the restrictive factory paper filters with an improved, high flow and reusable lifetime triple-layer Trifoam filter. Put simply, it’s the best High Flow Intake Filter you can buy for the new 3.0 TFSI engine.

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.
