MST Performance BMW 2, 3 & 4 Series N55 Engine M2 Air Intake Kit

MST Performance BMW 2, 3 & 4 Series N55 Engine M2 Air Intake Kit

If you want more from your BMW’s engine without a full-scale build, a quality air intake kit is one of the most straightforward and cost-effective upgrades you can make. This MST Performance induction kit is designed specifically for BMW’s N55 turbocharged engine, replacing the restrictive factory airbox with a free-flowing system that helps the engine breathe more efficiently.

The result is improved throttle response – meaning the engine feels more immediate and eager when you put your foot down – along with a more satisfying induction sound under acceleration. Dyno testing has shown gains of up to 12-14bhp, though real-world results will vary depending on the condition of your vehicle and any other modifications already fitted.

What’s Included

• Black powder-coated heat shield – helps keep hot engine bay air away from the intake
• Black powder-coated 4″ inlet pipe – the tube connecting the filter to your turbocharger
• 4″ red pleated dry air filter – easy to clean and reuse, no oiling required
• Full fitting kit with step-by-step instructions

Why It Makes a Difference

The standard BMW airbox is designed with noise reduction and emissions compliance in mind, which means it restricts airflow to some degree. This MST kit opens that up, allowing a greater volume of cooler, denser air to reach the turbocharger (the forced induction unit that pushes compressed air into the engine). More air means the engine can work more effectively, particularly when tuned or pushed hard.

The included heat shield is an important part of the system – it separates the filter from the heat generated by the engine, helping to ensure the intake draws in cooler air where possible. Cooler air is denser, which is better for performance.

The dry pleated filter is simple to maintain. Unlike oiled performance filters, it requires no messy re-oiling – just a clean with an air line or a gentle wash when needed.

Fitment

This kit is designed for BMW models fitted with the N55 turbocharged engine, covering the following vehicles from the 2012-2016 period:

BMW 135i (F20) – BMW 235i (F22) – BMW 335i (F30) – BMW 435i (F32) – BMW M2 (F87)

Use the vehicle lookup tool on this site to confirm compatibility with your specific model and build year, or check the Vehicle Fitment tab for full details before purchasing.

This is a well-rounded upgrade for any N55-powered BMW owner looking for a noticeable improvement in throttle response and a cleaner, more involving driving experience. It works well on standard cars and is equally at home on vehicles that have already had ECU (engine control unit) tuning or other performance modifications applied.
