Toyota Supra A90 / BMW Z4 B58 3.0L 4 inch Aluminium Air Intake System - Black

Product Overview

This 4 inch aluminium air intake system is made for the Toyota GR Supra A90 and the BMW Z4 sharing the B58 3.0L (2979 cc) turbocharged inline-six. With a large-diameter tube and open filter in place of the factory intake, it aims to give the turbocharger an easier breathing path and to bring out more of the turbo and induction sound. The black finish keeps the look understated.

Vehicle Compatibility

The supplier lists fitment for the Toyota Supra A90 and BMW Z4 with the B58 3.0L engine. The year information in the supplier data (2003-2004) does not match these models and appears to be an error. Fitment is supplier-stated and not independently verified, so please confirm compatibility before ordering.

Installation and Usage

Fitting involves removing the factory air box and ducting, installing the new tube and filter, and reconnecting all sensors and breather lines.
