MST Performance Air Intake Kit for BMW B58 3.0T Engines
The MST Performance intake kit is a straightforward upgrade that replaces the restrictive standard airbox on BMW B58 3.0T engines. By allowing more cold air to flow directly to the turbocharger, the engine can breathe more freely – which translates to improved throttle response and a noticeable improvement in power output.
Dyno testing has shown gains of up to 12-14bhp over a standard setup, though real-world results will vary depending on your vehicle’s state of tune and condition. Whether your car is running stock or already has engine management modifications, this intake is a well-regarded starting point for B58 performance builds.
What’s Included
- Black powder coated heat shield
- Black powder coated 4″ inlet pipe
- 4″ red dry pleated performance filter
- Silicone joiner
- Full fitting hardware and step-by-step instructions
Key Benefits
Improved throttle response – The freer-flowing intake path reduces lag between pressing the accelerator and feeling the engine respond, making the car feel more alive during normal driving and on harder acceleration.
Cold air feed to the turbo – Cold air is denser than warm air, meaning the turbocharger (the device that forces extra air into the engine to increase power) has more to work with. The heat shield helps keep heat from the engine bay away from the intake, maintaining a cooler, denser air charge.
Easy to maintain – The dry pleated filter requires no oiling and is simple to clean or replace, unlike some oiled cotton filters which need more regular attention.
Quality finish – The powder coated pipework gives a clean, durable appearance that holds up well under bonnet heat and looks the part on a B58 engine build.
This kit is designed for 2019+ BMW models fitted with the B58 3.0T engine, including the 340i. To confirm this part fits your specific vehicle, please use the vehicle lookup tool on this page or check the Vehicle Fitment tab for the full compatibility list before ordering.
