Front Mount Air Intake Ramair BMW M140i M240i 340i 440i B58

BMW B58 Silicone Front Mount Intake – Ramair Cone Filter – M140i M240i 340i 440i F Series GEN 1

Give your BMW B58 the airflow it deserves with this high-performance Silicone Front Mount Intake, designed specifically for the F-Series GEN 1 platform — including M140i, M240i, 340i, and 440i models.

This intake is equipped with a Ramair oiled foam cone air filter, a smart choice for both daily driving and motorsport use. Oiled foam filters are widely used in off-road and racing applications due to their superior dust and water resistance. Compared to paper or dry cotton filters, oiled foam repels water far more effectively, making it ideal for a front-mounted position. It's also fully washable and reusable, saving you money over time.

Unlike traditional setups, this front mount intake places the filter directly behind the kidney grille in a perpendicular position to incoming airflow, making it virtually impossible for water to saturate the filter to the point of engine hydrolock. After extensive testing, this design has proven to lower intake air temperatures to near ambient levels, even under spirited driving — meaning more power and better heat management without compromising safety. This is one of the safest and most efficient front-mount intake solutions on the market.

Built from 6-ply high-grade silicone, the intake pipe offers a perfectly smooth interior surface for optimal airflow. Unlike aluminum charge pipes, there are no internal welds, eliminating the risk of weld debris being drawn into the turbo — a common failure point in metal alternatives.
