Performance Air Filter for Audi A3/TT 2.0L TSFI Engine

Maximum Oxygen Density for the Audi 2.0L TFSI: The BMC Performance Induction Solution

Who It’s For: Engineered for Audi A3 and TT owners running the legendary 2.0L TFSI (EA113/EA888) powerplant who are tired of the stock engine’s strangled response under boost.

The Symptom: The factory intake system on your Audi is designed for silence and cost-efficiency, not peak volumetric efficiency. The standard paper filter acts as a physical wall, creating significant pressure drops as the turbocharger tries to pull air. This restriction results in increased turbo lag, a muffled engine note, and a noticeable drop-off in power as you climb the RPM range. When you’re pushing 15+ PSI of boost, that factory paper element simply cannot keep up with the CFM requirements of the 2.0L TFSI.

The Engineering Fix: This BMC High-Performance filter replaces the restrictive OEM paper element with a multi-layered cotton gauze system. By utilizing a "Full Moulding" process, BMC creates a single-piece filter without welded joints, eliminating potential failure points and ensuring a perfect seal within the airbox. The specialized low-viscosity oil coating captures impurities as small as 7 microns—significantly better than the 10-micron limit of factory filters—while simultaneously increasing air velocity. This allows your turbocharger to reach target boost faster and maintain it with less effort, resulting in sharper throttle snap and a genuine induction growl.

Why Mechanics Choose This Kit

• The Power: By reducing the intake pressure drop, this filter allows the 2.0 TFSI to breathe freely, specifically benefiting the 200HP to 265HP variants by optimizing the air-to-fuel ratio during high-load scenarios.
• The Sound: It unlocks the natural "spool" and "diverter valve" acoustics of the Audi turbo system without the obnoxious drone of a cheap open-pod intake.
• The Build: Featuring an epoxy-coated alloy mesh for oxidation resistance and a high-durability rubber housing that maintains its shape even under the extreme heat of the A3/TT engine bay.
