BMW 340i Turbo Intake Hose Kit with RamAir Filter and Heat Shield – Performance B58 Intake Upgrade for M140i, M240i, 340i, 440i
Unlock sharper throttle response, stronger mid-range torque and addictive turbo spool sound with this BMW B58 performance intake kit. This direct-fit turbo intake hose kit features a handmade 6-ply silicone intake hose, an aluminium machined AFM housing with bracket, a large 90 mm RamAir performance filter and a custom B58 heat shield for lower intake temps and reliable power. Perfect for BMW 340i intake upgrades as well as M140i intake, M240i intake and 440i intake applications.
Built to flow more air than the restrictive factory intake pipe, the fluoro lined silicone hose resists discolouration and heat soak, while the heat shield helps keep hot engine bay air away from the filter. Expect a sharper throttle, quicker turbo response and the satisfying induction and turbo noises enthusiasts love.
