Performance Air Filter for Audi A3 Q3 TT 2.5 TSI TTRS 2.5 RSQ3 2.5 TFSI RS3 Engines

Wake Up the 5-Cylinder DAZA: BMC High-Flow Performance Filter

Who It’s For: Engineered for Audi RS3, TTRS, and RSQ3 owners running the legendary 2.5L TFSI powerplant who want to optimize turbo efficiency without sacrificing filtration quality.

The Symptom: The factory air intake on the 2.5L Inline-5 is equipped with a thick, restrictive paper element designed for long service intervals and maximum sound dampening. For a high-output turbocharged engine like the DAZA or DNWA, this creates a significant pressure drop across the intake tract. When you’re chasing boost, that restrictive paper filter forces the turbocharger to work harder to pull the same volume of air, which can lead to higher intake air temperatures and a slight hesitation in throttle snap when exiting a corner or merging on the highway.

The Engineering Fix: This BMC replacement filter utilizes a multi-layered cotton gauze media, pre-soaked in a low-viscosity oil to catch impurities as small as 7 microns. By replacing the dense paper with high-flow cotton, we reduce the resistance the turbocharger faces. The "Full Moulding" construction means the entire filter is produced from a single mould with no welded joints, ensuring it won’t crack or leak under the high-vacuum conditions found in a tuned 400HP+ RS-series engine. This results in a more immediate boost response and a noticeable increase in the 5-cylinder’s signature induction growl.

Why Mechanics Choose This Kit

• Precision Filtration: Unlike many "performance" filters that let larger particles through, this media catches debris down to 7 microns, providing better protection than the 10-micron OEM paper standard.
• Structural Integrity: The epoxy-coated alloy mesh protects the cotton layers from petrol fumes and oxidation, while the durable rubber housing ensures a perfect, airtight seal inside your factory airbox.
• Sustainable Performance: This is the last filter you’ll buy. It is fully washable and regenerable using a BMC service kit, maintaining "like-new" airflow for the life of the vehicle.
