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.
Our 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.
The result? More mid-range power and improved economy, without wrecking your warranty.
