MST Performance Air Intake Kit & Turbo Inlet Pipe – BMW F22, F30 & F32 125i, 228i, 320i, 328i & 428i (N20 Engine)
This intake kit from MST Performance is a straightforward upgrade for BMW owners looking to improve airflow to the engine on their F22, F30 or F32 model. It replaces the factory airbox with a free-flowing induction setup paired with a turbo inlet pipe, helping your N20 turbocharged engine breathe more efficiently.
The result is improved throttle response – meaning the engine reacts more crisply when you press the accelerator – along with modest power gains and a more engaging induction sound under acceleration.
What Does This Kit Do?
The standard BMW airbox is designed to balance noise suppression and packaging, not outright performance. This MST kit removes that restriction by routing cooler, denser air more directly to the turbocharger (the forced induction unit that compresses air into the engine). The included turbo inlet pipe further improves airflow between the intake and the turbo itself, reducing any bottleneck in the system.
Dyno testing – where a vehicle is run on a rolling road to measure power output – has shown gains of up to 12-14bhp on suitable vehicles. Please note: actual gains will vary depending on your vehicle’s condition, any existing modifications, and tuning state.
What’s Included
- Black powder-coated heat shield
- Black powder-coated inlet pipe
- Red pleated dry performance air filter
- Silicone joiner
- Turbo inlet pipe
- Full fitting hardware and step-by-step instructions
Key Benefits
The dry pleated filter is easy to maintain – no oiling required, unlike some performance filters – and the powder-coated components give the engine bay a clean, purposeful finish. The heat shield helps direct cooler air to the intake, which is important for maintaining consistent performance, as cooler air is denser and more oxygen-rich than warm air.
Fitment
This kit is designed for 2012 and later BMW models fitted with the N20 four-cylinder turbocharged petrol engine, covering the F22, F30 and F32 body styles across the 125i, 228i, 320i, 328i and 428i variants. Use the vehicle lookup tool on this site or check the Vehicle Fitment tab to confirm compatibility with your specific model before ordering.
