MST Performance Induction Intake Kit For BMW M5 & M8 inc. Competition Models

MST Performance Induction Intake Kit for BMW M5 and M8 – Including Competition Models (MST-BW-F90M5-BK)

If you own a BMW M5, M8, or one of their Competition variants, this induction kit from MST Performance is a straightforward way to improve airflow into the engine, sharpen throttle response, and add a more involving induction sound – all with a direct-fit installation.

The standard airbox on these cars does a reasonable job, but it is designed with refinement and noise reduction in mind rather than outright airflow. Swapping it for this MST kit removes that restriction and lets the engine breathe more freely, which translates into modest but genuine performance gains.

What It Does

The kit replaces both factory airboxes (this is a twin-turbo V8 engine, so there are two intake sides to feed) with high-flow components designed to move more air to the turbos. More air means the engine can work more efficiently, particularly under hard acceleration. MST quote gains of between 10 and 12 horsepower over the standard setup – a realistic figure for a quality intake kit on a well-engineered engine like the S63 unit found in these cars.

The laser-cut heat shields are an important part of the kit. Heat soak – where hot air from the engine bay is drawn into the intake rather than cooler outside air – can reduce the benefit of an intake upgrade. The shields help manage this by shielding the filters from the worst of the engine heat.

What You Get

• 2 x black powder-coated heat shields
• 2 x black powder-coated inlet pipes
• 2 x red pleated high-flow air filters
• 2 x black silicone intake hoses
• Full fitting hardware and step-by-step installation instructions

The red pleated filters are easy to remove and clean, so maintenance is simple. The finish throughout is clean and purposeful – the kind of thing you would not mind seeing under the bonnet.

Fitment

This kit is designed to fit the BMW M5 (F90), M5 Competition, M8, M8 Competition, and M 850i. Please use the vehicle lookup tool on this site or check the Vehicle Fitment tab to confirm this kit is correct for your specific model and engine variant before ordering.

Installation uses the existing mounting points and includes all necessary hardware, making it accessible for a competent home mechanic, though professional fitting is always an option if you prefer.

Overall, this is a well-made, properly engineered intake upgrade for one of BMW’s most capable performance cars. It will not transform the vehicle on its own, but as part of a wider setup – or simply as a first upgrade – it delivers a noticeable improvement in response and character alongside those real-world power gains.
