MST Performance Silicone Turbo Inlet Hose – BMW G20 320i / 330i B48 2.0T (2019+)
The standard turbo inlet hose on the BMW B48 engine is made from rigid plastic and is designed primarily with cost in mind, not performance. Over time it can also become brittle and prone to cracking. This silicone turbo inlet hose from MST Performance is a direct replacement that improves airflow into the turbocharger, helping the engine breathe more freely.
The turbo inlet hose connects the air filter housing to the inlet of the turbocharger. A less restrictive inlet means the turbo can spool up (reach operating speed) more quickly, which reduces that brief hesitation you sometimes feel before the power kicks in – commonly known as turbo lag. The result is a throttle response that feels sharper and more immediate, whether you are driving on a standard tune or have already had the car mapped.
What is Included
- MST Performance black silicone turbo inlet hose
- CNC machined aluminium fittings
Why Choose Silicone Over Standard Plastic?
Silicone is flexible, heat-resistant, and built to last. Unlike the original plastic hose, it will not crack or harden with age and heat cycles. The smoother internal surface also helps air flow more efficiently towards the turbo, rather than being disrupted by a rough or restrictive bore. MST Performance manufacture this hose to fit precisely in place of the original, so no cutting, drilling, or modification is needed.
This is a particularly worthwhile upgrade if your B48 engine has already been remapped or tuned, as a tuned engine demands more air and benefits more noticeably from improved inlet flow. That said, it is equally at home on a completely standard car, where it provides a solid foundation for any future modifications.
Important: This inlet hose is designed specifically for the BMW G20 320i and 330i fitted with the B48 2.0T engine from 2019 onwards. Please use the vehicle lookup tool on this page or check the Vehicle Fitment tab to confirm compatibility with your specific car before purchasing.
