Cold Air Intake for Audi A3 & VW Golf Jetta (2004-2008) 2.0L Turbo Engine

Maximize Volumetric Efficiency: High-Flow Intake for the Audi A3 2.0T EA113

Who It’s For: Engineered for 2004-2008 Audi A3 owners running the EA113 (BPY/AXX) 2.0L turbocharged powerplant who are tired of the stock sluggishness and muffled turbo response.

The Symptom: The factory intake on the 2.0T FSI engine is a notorious bottleneck, often integrated directly into a heavy, heat-soaking engine cover. This design uses a restrictive paper filter and a series of internal plastic baffles meant to silence the engine, but they ultimately choke the turbocharger’s ability to breathe. You’ll notice this as a delay in boost threshold (turbo lag) and a lack of top-end pull when you’re trying to merge onto the highway or power out of a corner.

The Engineering Fix: Our system deletes the restrictive factory "suitcase" and replaces it with a mandrel-bent T-304 aluminum induction tube. By maintaining a constant internal diameter and smoothing out the airflow path, we significantly reduce intake air turbulence. The included heat shield isolates the high-flow cone filter from the radiant heat of the engine bay, ensuring a denser oxygen charge enters the turbo compressor. This results in a faster spool time, a sharper throttle snap, and a visceral induction roar that lets you actually hear the diverter valve and turbo working.

Why Mechanics Choose This Kit

• Optimized Power Band: This system is designed to provide a 7-10% increase in horsepower and 6-8% increase in torque by improving the engine’s volumetric efficiency in the mid-to-high RPM range.
• Aggressive Acoustics: Replaces the sterile factory silence with a deep, sporty induction note that highlights the 2.0T’s turbocharged character.
• Premium Construction: Features lightweight, polished T-304 aluminum piping and a high-flow, washable, and reusable cotton-media cone filter for long-term durability.
