Summary
The M140i and M240i built cult followings on one engine: the 3.0T B58. This MST Performance cold air intake system lets it breathe and be heard, replacing the restrictive standard air box with a black powder-coated inlet pipe and heat shield, a red dry pleated filter and a silicone joiner. The design feeds cold air towards the turbocharger for sharper throttle response and a proper induction note. One part covers B58 1, 2, 3 and 4 Series F-chassis cars from 2016 on, with a full fitting kit and step-by-step instructions included.
Best For
- M140i and M240i owners unlocking the soundtrack the B58 hides
- 340i and 440i drivers covered by the same F-chassis fitment
- Tuned B58 builds pairing software with colder, freer airflow
- A showpiece engine-bay upgrade with the powder-coated finish
Cold Air, Straight To The Turbo
Heat is the enemy of intake charge, so this kit pairs its heat shield with a route designed to deliver cold air straight to the turbocharger. The design targets improved throttle response and a stronger induction note over the standard restrictive air box, on standard cars and already-tuned ones alike. The dry pleated filter is easy to maintain, and the powder-coated hardware makes the engine bay look as intentional as it sounds.
