Set your V8 free to breathe better and operate more efficiently.






Looking for a simple, warranty-friendly R8 upgrade?

Our pair of RacingLine High-Flow Intake Filters for the Audi R8 V8 4.2 replace the restrictive factory paper filters with improved, high flow and reusable lifetime triple-layer Trifoam® filters. Designed to fit inside the standard R8 air boxes for improved airflow and performance.

Put simply, it’s the best Hi-Flow Intake Filter you can buy for your R8.

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 engine to breathe better and operate more efficiently – improve the 4.2 engine’s airflow, and power gains will follow. 

By removing the inevitable restrictions that the standard paper filters give, the RacingLine Hi-Flow Intake Filters allow a worthwhile increase in airflow through to the V8.  


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


Each filter construction is hand-made in the UK for the reassurance of high quality together with exceptional dust-loading properties.


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


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

Stainless steel open mesh supports the foam to provide an airtight seal inside the standard airbox.

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

The higher flow of clean air gives much more consistent and efficient power delivery.

Developed and proven on our own R8 4.2 GT Endurance racing car.

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.
