MST Performance Intake Kit – BMW S58 M3/M4 Competition G80 & G82 (2021+)
The MST Performance intake kit is a direct replacement for the standard airbox on the 2021+ BMW M3 and M4 Competition (G80/G82), and the G87 M2, all running the S58 engine. The factory airbox is designed with noise refinement and emissions compliance in mind, which means it can restrict the amount of air reaching the engine. This kit removes that restriction, allowing a freer, cooler airflow straight to the turbocharger – the component that forces air into the engine to boost power.
The result is improved throttle response (the engine feels more immediate when you press the accelerator), a more purposeful induction sound, and measurable power gains. MST’s own dyno testing (rolling road performance testing) shows gains of up to 12-14bhp, though real-world results will vary depending on the state of tune and condition of the vehicle.
This kit works well on both standard and already-tuned vehicles, making it a solid first modification or a useful addition to an existing setup.
What Makes It Different From the Standard Setup
The standard BMW airbox prioritises refinement over performance. The MST kit replaces it with a black powder-coated heat shield and inlet pipe, which helps keep heat away from the incoming air. Cooler air is denser, and denser air contains more oxygen – which the turbocharger can use to produce more power. The 4-inch red pleated filter (a dry, serviceable filter rather than an oiled one) flows more air than the standard paper element and is straightforward to clean and maintain over time.
What’s Included
- Black powder-coated heat shield
- Black powder-coated 4″ inlet pipe
- 4″ red dry pleated performance filter
- Silicone joiner
- Full hardware fitting kit with step-by-step instructions
Installation is designed to be straightforward, with all necessary hardware included and clear instructions provided. No specialist tools are required for a standard fit.
Important: This kit is designed specifically for S58-engined BMW models including the G80 M3 Competition, G82 M4 Competition, and G87 M2. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific model before purchasing.
