BMW B58 Turbo Intake Hose Kit with RamAir Filter and Custom Heat Shield for M340i, M140i, M240i, 340i, 440i
Unlock sharper throttle response, stronger mid-range torque and addictive turbo induction sound with this premium BMW B58 intake upgrade. This intake hose and AFM housing kit with RamAir filter and custom heat shield is designed to maximise airflow to your turbo while reducing heat soak for reliable, repeatable performance. We have run this setup on our own B58 cars and customer cars, and the feedback has been excellent.
Handmade from 6 layers of silicone and fluoro lined to prevent discolouration, the intake hose delivers superior durability and flow. The aluminium machined AFM housing ensures precise fitment and smooth, consistent metering. Paired with a high-flow 90 mm RamAir performance filter and a custom B58 heat shield, this is an ideal upgrade for anyone chasing better response, more induction noise and a cleaner engine bay.
