BMW B58 Turbo Intake Hose Kit with RamAir Filter and Custom Heat Shield
Upgrade the airflow on your BMW B58 with this high quality intake hose and AFM housing kit, complete with a 90 mm RamAir performance filter and a custom B58 heat shield. Designed to replace the restrictive factory intake hose on B58 models, this induction upgrade transforms throttle response, improves torque delivery and unlocks extra turbo sound. We have installed and run this kit ourselves and customer feedback has been consistently positive for sharper response and a more engaging drive.
Built from a handmade 6 layer silicone construction and fluoro lined to prevent discolouration, this intake hose is engineered to handle heat, boost and oil vapour for long term reliability. The aluminium machined AFM housing maintains correct sensor placement and smooths airflow for consistent performance. The custom B58 heat shield helps reduce heat soak, feeding the RamAir filter with cooler air.
