Racing Line High-Flow Panel Air Filter Pair for Audi R8 R8 Spyder V10 5.2 - VWR119052 - The perfect starting point for your Audi R8's V10 5.2 TFSI power upgrades, Racing Line's Trifoam® High Flow Air Filters use the exact same filter material as our intake systems do. A simple drop-in replacement for your factory paper filter, giving a valuable boost to engine efficiency as a perfect complement to either the stock engine or those running Stage 1 calibrations. Looking for a simple, warranty-friendly upgrade for your car? Set your naturally aspirated engine free by allowing it to breathe better and operate more efficiently with Racing Line’s High-Flow Air Filters, available for the mighty V10 5.2 TFSI Audi R8. They replace the restrictive factory paper filters with a pair of improved, high flow and reusable lifetime triple-layer Trifoam® filters. Put simply, they are the best High-Flow Air Filter you can buy. The filters offers OEM-standards of design, quality, materials and construction, hand-made in the UK. Fit like a factory part; last like a factory part. A stainless steel open mesh, surrounded by a poured polyurethane moulded seal provides an airtight seal against the standard airbox. Removing the inevitable restrictions that the standard paper panel filters give, Racing Line’s Panel Filters allow a small but worthwhile increase in airflow through to the turbo. And by allowing your engine to breathe better and operate more efficiently will improve the engine’s airflow, and power and fuel economy gains will follow. The Trifoam® filter material itself ensures an exceptionally high level of filtration – it’s the very same material technology as some F1 engines use. Our tests have shown that it can deliver an additional 25NM of torque on a standard 5.2 TFSI engine. A small but very worthwhile difference.
