Racingline High-Flow Panel Air Filter – Audi TT RS (8S) & RS3 (8V)
Help your Audi TT RS or RS3 breathe more freely with the Racingline High-Flow Panel Air Filter. This is a direct replacement for the standard paper filter that sits in your factory airbox, designed to reduce airflow restriction and let your 2.5 TFSI five-cylinder engine work more efficiently.
The OEM paper filter is known to be a bottleneck on these high-performance engines. Swapping it for the Racingline filter is one of the simplest upgrades you can make: it doesn’t require any modifications, doesn’t affect your factory warranty, and takes only a few minutes to fit.
What the Trifoam® Filter Does
Racingline’s filter uses a unique three-layer foam construction, known as Trifoam®. Each layer has a different density, working together to trap dust and dirt particles while still allowing significantly more air through than a standard paper element. The result is better filtration and less restriction, which is exactly what a turbocharged engine wants.
More airflow means your engine and turbo work less hard to draw in the air they need. On the road, this translates into a small but genuine improvement in mid-range response and, in many cases, slightly better fuel economy when driven sensibly.
Key Benefits
- Trifoam® technology: three layers of foam for the right balance of filtration and flow
- Direct replacement: drops straight into the factory airbox with no modifications
- Warranty-friendly: no impact on your Audi manufacturer warranty
- Reusable for life: simply clean, re-oil and refit rather than throwing it away
- Hand-made in the UK: built to consistent quality standards by Racingline
Reusable and Built to Last
Unlike a disposable paper filter, the Racingline panel filter is designed to be washed, re-oiled and refitted as part of your regular servicing. A standard air filter cleaning and oiling kit is all you need to keep it performing as intended for the life of the car.
Vehicle Fitment
This filter is designed specifically for the 2.5 TFSI five-cylinder engine fitted to the Audi TT RS (8S) and Audi RS3 (8V/8V.2). Please use the vehicle lookup tool on the Racingline Shop or check the Vehicle Fitment tab to confirm compatibility with your specific car before ordering.
Realistic Expectations
A panel filter upgrade is a sensible first step rather than a headline power modification. On its own, expect a modest improvement in throttle response and breathing rather than a large jump in peak power. It works particularly well as part of a wider intake or software setup, where reduced restriction allows other upgrades to perform at their best.
As an authorised UK retailer of Racingline Performance, we supply only genuine Racingline products, manufactured and tested to the brand’s own standards.
