MMR Silicone Intake Hose for BMW B58 – the essential intake upgrade for BMW M140i, M240i, 340i and 440i F Series. This high quality silicone turbo inlet hose smooths airflow from the airbox to the turbo, enhances induction noise, and smartens up the engine bay with a deep gloss black finish. A direct replacement for the restrictive factory plastic bellows pipe, it is a simple, effective way to unlock airflow on your B58.
We have fitted and tested this hose on our own cars and for customers, and the feedback is consistently positive. Expect a smoother, less turbulent intake path that helps the engine breathe more freely and sounds great when you get on the throttle.
Why choose the MMR Silicone Intake Hose?

- Smoother, larger diameter internal bore for improved airflow to the turbo

Performance focused airflow upgrade
This silicone intake hose replaces the restrictive OEM bellows, removing turbulence before the turbo and delivering a worthwhile improvement in intake efficiency. It works brilliantly with the standard airbox and turbo elbow, especially when paired with an MMR High Flow Filter, and really shines alongside the MMR Air Intake or other aftermarket intakes. Without this hose, you can leave gains on the table even after fitting a high flow intake.
Built to last
The hose features reinforced silicone elements in critical areas for rigidity under heat and load, while still allowing the right amount of compliance to accommodate normal engine movement. Fit it once and enjoy reliable performance.
Fitment and installation
Compatible with BMW M140i, M240i, 340i, 440i with the B58 engine in the F Series generation. Installation typically takes around 10 minutes. Hose clips are not included – simply reuse the originals.
