Set your 3.0 TFSI supercharged engine free by allowing it to breathe better and operate more efficiently.






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 lifetime 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.


Our Trifoam® material allows us to sandwich three different foams together for the perfect filtration and minimum restriction.


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.


Trifoam® filter construction, triple-layer laminate of open-cell polyurethane foam.

Aluminium spinning supporting a reinforced internal plastic cage. 

An exceptionally high level of filtration – the very same technology as some F1 engines use.

Tests show it delivering an additional 20NM of torque on a standard 3.0 TSI engine. A small but worthwhile difference to the feeling of mid-range power.

The filter element is at the heart of your RacingLine intake. And, as with all specialised parts developed for high performance and motorsport use, the filter element must be a part of your regular maintenance schedule.


Our Oil and Cleaner Kit will help you keep your filter in peak condition at all times and ensure that the complex triple-layer foam continues to deliver its power and filtration benefits for many years.


It’s a simple procedure. The filter element requires cleaning and re-oiling every 10,000 miles/16,000 km, and inspection at least every 12 months. If your car is regularly used in a dusty environment, we advise that you clean and re-oil your filter more regularly.


It’s important that only this RacingLine Oil and Cleaner Kit are used, as they've been specially formulated to work with our foam air filter material.
