MST Performance Air Intake Kit & Inlet – Toyota Supra & BMW Z4 2.0 B48 (MST-TY-SUP03L)
This induction kit from MST Performance is designed as a direct upgrade over the standard airbox on the MK5 Toyota Supra and BMW Z4 fitted with the 2.0-litre B48 turbocharged engine. It increases the volume of cool air reaching the turbocharger, which helps the engine breathe more freely and can improve both performance and throttle response – that is, how quickly the engine reacts when you press the accelerator.
It is a well-suited upgrade whether your car is completely standard or has already had other modifications such as a tune or remap.
What Are the Benefits?
By replacing the restrictive factory airbox with a freer-flowing intake setup, this kit allows more cold air to reach the turbo more efficiently. The result is a more responsive engine, a noticeable improvement in induction sound (the intake noise you hear when accelerating), and a measurable increase in power. Dyno testing – using specialist equipment to measure power output on a rolling road – has shown gains of up to 12-14bhp, though results will vary depending on the vehicle’s state of tune and condition.
The heat shield helps keep warm engine bay air away from the filter, so the air entering the intake stays as cool and dense as possible. Cooler, denser air contains more oxygen, which helps the engine and turbo perform at their best.
What’s Included in the Kit?
- Black powder-coated heat shield
- Black powder-coated inlet pipe
- Red dry pleated performance air filter
- Silicone joiner
- Full fitting hardware and step-by-step instructions
The dry pleated filter is straightforward to clean and maintain, with no oil required – unlike some performance filters. The powder-coated finish on the heat shield and inlet pipe gives a clean, durable appearance under the bonnet.
