MST Performance VW Golf Mk5 R32/A3 VR6 3.2L Air Intake Kit

MST Performance Air Intake Kit – VW Golf Mk5 R32 / Audi A3 VR6 3.2L

This air intake kit from MST Performance is a straightforward upgrade for the VW Golf Mk5 R32 and Audi A3 VR6 3.2L. It replaces the standard airbox with a freer-flowing setup, allowing the engine to breathe more easily – which in turn can improve throttle response, increase power output, and give that satisfying induction sound under acceleration.

MST Performance are a well-regarded name in the performance intake market, building kits that offer a noticeable real-world improvement without requiring major modifications. This kit is suitable whether your car is standard or already running a tune.

What It Does

The standard airbox on the Golf Mk5 R32 and A3 VR6 is designed with noise reduction and cost in mind, not outright performance. This MST kit removes that restriction by using a larger, free-flowing filter and a smoother intake pipe, allowing more air to reach the engine more quickly. More air, combined with fuel, means better combustion – and that translates to improved throttle response and potential power gains.

Dyno testing (testing on a rolling road to measure power output) has shown gains of up to 12-14bhp, though results will vary depending on the individual vehicle and its state of tune.

What’s Included

• Black powder-coated heat shield to help keep intake temperatures down
• Black powder-coated 4-inch inlet pipe, mandrel-bent for smooth airflow
• 4-inch red pleated performance air filter using nano-fibre dry filter technology
• Full fitting kit with step-by-step instructions

Build Quality

The intake pipe is constructed from 6061 aluminium – a lightweight, durable alloy commonly used in performance applications. The mandrel-bending process (a technique that keeps the pipe’s internal diameter consistent around bends, rather than collapsing it) ensures airflow stays smooth throughout the pipe. The nano-fibre dry filter provides excellent filtration without needing oil treatment, keeping maintenance simple.

MST Performance back this kit with a limited lifetime warranty, which reflects the quality of materials and construction used.
