PRODUCT DESCRIPTION
The perfect starting point for your 2.5 TFSI power upgrades, RacingLine’s Trifoam® high-flow panel filter uses the same filter material as our intake systems. A simple, direct replacement for your factory paper filter, providing a valuable increase in engine efficiency as a perfect complement to both stock engines and those running Stage 1 calibrations. Looking for a simple, warranty-safe upgrade for your car? Free up your engine by allowing it to breathe better and operate more efficiently with a RacingLine high-flow panel air filter, available for Audi RS3 and TTRS MQB 2.5 TFSI ‘DAZA’. Replace the restrictive factory paper filters with an upgraded, high-flow, lifetime-reusable triple-layer Trifoam® filter. In short, it’s the best panel air filter you can buy. This filter offers OEM standards of design, quality, materials, and construction, handmade in the UK. Fits like a factory part; lasts like a factory part. An open-mesh stainless steel back, surrounded by a poured polyurethane molded seal, gives an airtight seal against the standard airbox. By removing the inevitable restrictions of the standard paper panel filter, RacingLine's panel filter allows a small but significant increase in airflow to the turbo. And by allowing your engine to breathe better and operate more efficiently, it will improve engine airflow, translating into power gains and fuel economy. The Trifoam® filter material ensures an exceptionally high level of filtration; it's the same material technology used by some F1 engines. Our testing has shown it can provide an extra 20Nm of torque on a standard 2.5 TFSI engine. A small, but very worthwhile difference.
