MMX Silicone intake hose | MINI F56 | GP3 | BMW F4x | M135i

The MMX silicone intake hose is engineered for the B48A20T1, the highest-output variant of BMW’s B48 platform, fitted to the MINI JCW GP3 and BMW M135i. It replaces the factory plastic bellows pipe between the airbox and intake backpipe with a reinforced silicone hose, engineered to smooth airflow into the turbo, improve induction acoustics, and present a cleaner engine bay.

The large diameter, smooth-flowing hose is constructed from high quality silicone, with reinforced elements embedded in critical areas to provide rigidity and resist deformation under load or heat.

Because the engine can move considerably under load, particularly at the GP3 and M135i’s output level, the hose is engineered with just enough compliance to accommodate that movement without placing stress on the intake or backpipe connections.

Fully compatible with the OE airbox and elbow, or with the MMX resonator delete pipe for those looking to build a complete induction upgrade. Supplied in a deep gloss black finish, it retains a stepped inlet and outlet to maintain a constant bore with smooth transitions, promoting maximum airflow.
