Looking for a simple, warranty-friendly upgrade for your car?
Our High-Flow Intake Filter for the B8/8.5-platform Audi S4 and S5 replaces the restrictive factory paper filters with an improved, high flow and reusable triple-layer Trifoam® filter. Put simply, it’s the best High Flow Intake Filter you can buy for the 3.0 V6 supercharged 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, 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 supercharger.
TRIFOAM® FILTER
RacingLine's Trifoam® material allows us to sandwich three different foams together for the perfect filtration and minimum restriction.
HAND-MADE IN UK
Each Trifoam® filter construction is hand-made in the UK for perfect quality.
EFFICIENCY GAINS
The result? More mid-range power and improved economy, without wrecking your warranty.
