MST 2021+ BMW G80 G82 M3 M4 Competition S58 Cold Air Intake System + Inlet (BW-S5806)

To further enhance the performance potential of the S58 engine, we go beyond simply improving airflow efficiency—we redefine the upper limits of the entire intake system from the ground up. The system features a massive 152 mm high-flow air filter paired with a dual intake pipe configuration. With the combined advantage of enlarged piping and increased filtration surface area, overall airflow capacity is significantly improved, reducing flow restriction and increasing air velocity—ensuring that air supply is no longer a limiting performance factor. Features 6" intake tube for improved airflow Dual 6" high-performance filters Larger turbo inlet for less restriction Maximizes engine airflow Laser-cut heat shield blocks engine heat Better throttle response and sound Compatible with stock or tuned maps Reusable high-flow filters, easy to maintain Fits 2021+ BMW G80 G82 M3 M4 Competition S58
