MST Performance Induction Kit – BMW 1, 2, 3 & 4 Series 2.0T B48 Engine
This induction kit from MST Performance is a direct replacement for the standard airbox on BMW B48 2.0T engines. It increases the flow of cold air into the engine, which helps improve throttle response, add a modest power gain, and gives the intake a more audible sound under acceleration.
The B48 engine’s factory airbox is designed with noise reduction and emissions compliance in mind, not outright performance. Swapping it for this MST kit removes that restriction and feeds the turbocharger (the forced-induction unit that pushes compressed air into the engine) with a more direct, cooler air supply.
What’s Included
- Black powder-coated heat shield and inlet pipe (with MAF – Mass Air Flow sensor – housing)
- Black silicone inlet hose
- Red dry pleated performance air filter
- Full fitting hardware and step-by-step instructions
Performance & Benefits
MST quote dyno-tested gains of up to 12-14bhp on the B48 2.0T engine. These figures are a maximum recorded result and will vary depending on your vehicle’s state of tune, condition, and other modifications. On a standard car, real-world gains will likely be at the lower end of that range – but the improvement in throttle response and intake sound is noticeable even on an untuned vehicle. If your BMW is already remapped or modified, the benefits are typically more pronounced.
The included heat shield helps isolate the filter from engine bay heat, keeping intake temperatures lower and the air denser – which is what your engine needs for efficient combustion. The dry pleated filter requires no oiling and is easy to clean and maintain over time.
Fitment
This kit is designed for BMW B48 2.0T engines found across the 1 Series, 2 Series, 3 Series, and 4 Series model ranges from 2016 onwards. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific model and engine variant before purchasing.
Installation is straightforward and designed to be completed with basic hand tools using the included instructions, making it a practical choice for a home garage fitting or a quick job for a workshop.
