MMR Silicone intake hose for BMW B58 The MMR Performance silicone intake hose for B58-powered F-series BM Ws has been designed to smooth the airflow from intake into the turbo, enhancing induction noise and even improving engine bay aesthetics. Smooth your airflow path to the turbo with the MMR Silicone intake hose. The MMR silicone intake hose is a great upgrade when installed with the standard turbo elbow and airbox, and ideally paired with an MMR high-flow air filter, but really gives greatest gains when paired with the MMR air intake or other aftermarket intakes. A simple fitment, it replaces the entire restrictive factory plastic ‘bellows’ pipe between the airbox and the turbo inlet. By removing the standard plastic pipe's restrictive and turbulent airflow path, our silicone intake hose gives a worthwhile power gain. The large diameter smooth-flowing hose is constructed from high quality silicone. It has been carefully developed with reinforced silicone elements embedded in critical areas to offer great rigidity to prevent deformation under load or heat. But crucially, as the engine can move considerably under load, the MMR hose allows just the right amount of compliance to allow for adequate engine movement without causing damage to the intake itself. Features Large diameter smooth-flowing hose constructed from high quality silicone. Allows for adequate engine movement, without causing damage to the intake itself. Increased engine performance. Enhanced induction noise. Kit complete with everything you need. Fitment for OEM airbox, MMR air intake or aftermarket intakes. Additional Information Supplied in a deep gloss black finish and easily DIY installed in minutes, the MMR intake hose also features a stepped inlet and outlet to ensure a constant bore with smooth transitions to promote maximum airflow. Fitting Information Fitting is very straightforward and installed in around 10 minutes, and easily returned to standard, should you ever wish.
