BMW M140i M240i 340i 440i B58 Turbo Intake Hose Kit with RamAir Filter and Custom Heat Shield
Unlock sharper throttle response, stronger midrange torque and addictive turbo induction sound on your BMW B58 with this performance intake upgrade. This kit pairs a handmade 6‑ply silicone turbo intake hose with a precision aluminium machined AFM housing and bracket, a high‑flow 90 mm RamAir cone filter and a custom 55 Tuning B58 heat shield. It is a proven, direct‑fit upgrade for the M140i, M240i, 340i and 440i that transforms drivability and sound.
We have installed and used this kit ourselves and customer feedback has been consistently excellent. On healthy cars we have seen around 8 to 10 whp with this intake fitted alone, alongside noticeably crisper throttle response and improved spool. The fluoro‑lined silicone construction resists discolouration and heat, while the heat shield helps separate the filter from hot engine bay air for dependable performance.
