B58 Intake Kit for BMW F Series M240i/340i/440i

This is RVNG's 2.0 update to their popular F-Series B58 3.0L intake for the M140i, M240i, 340i, and 440i — a complete replacement for the OEM airbox, designed to be the largest, highest-flowing intake on the market with full heat-shield protection.

It starts with a high-flow air filter feeding a 3.5" aluminum pipe that mates cleanly to the turbo inlet — no restrictions. A full boxed heat shield keeps intake temps as low as possible. With no extra tuning, peak gains run 12 to 20HP (fuel and elevation dependent), with power and torque across the band and an aggressive, race-inspired sound. This revised version adds a more rigidly mounted inlet pipe and a better-sealing heat shield for strong performance with no CEL.
