MST Performance Toyota Supra A90/BMW Z4 (G29) B58 Induction Kit

MST Performance Toyota Supra A90 / BMW Z4 (G29) B58 Induction Kit

If you want more from your Toyota Supra A90 or BMW Z4 G29, upgrading the air intake is one of the most straightforward improvements you can make. This induction kit from MST Performance replaces the restrictive factory airbox with a freer-flowing setup, giving the B58 turbocharged engine easier access to cold, dense air – which is exactly what a turbo needs to work at its best.

The result is improved throttle response (the engine reacts more sharply when you press the accelerator), a more satisfying induction sound under load, and measurable power gains on both standard and already-tuned vehicles.

What It Does and Why It Matters

Your car’s standard airbox is designed with compromise in mind – it keeps things quiet and meets emissions requirements, but it restricts how freely air can reach the turbocharger. This MST Performance kit opens that restriction up. A larger, high-flow pleated filter draws in more air, the black silicone intake pipework routes it efficiently, and the powder-coated heat shield helps keep intake temperatures down by separating the filter from engine bay heat. Cooler, denser air going into the turbo means better combustion and more consistent performance.

Dyno testing has shown gains of up to 12-14bhp, though real-world results will vary depending on the state of your vehicle and any existing modifications.

What’s Included

• Black powder-coated aluminium heat shield
• Black silicone intake pipe
• Black inlet pipe
• 6″ red dry pleated performance filter
• Full fitting hardware and step-by-step instructions

Easy to Fit, Easy to Maintain

The kit is designed for a straightforward installation without specialist tools, and the dry pleated filter is simple to clean and maintain – no oiling required, unlike some performance filters. This makes it a practical long-term upgrade rather than just a one-time fit and forget.

Whether your Supra or Z4 is running standard power or has already had an ECU remap (a software modification to the engine’s computer), this kit offers a genuine, usable improvement.

Fitment: This kit is designed for the Toyota Supra A90/A91 and BMW Z4 (G29) equipped with the B58 turbocharged petrol engine. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific model and year before purchasing.
