This Turner Motorsport charge and boost pipe upgrade kit replaces both the hot-side and cold-side factory plastic charge pipes on the N55 engine with a durable 6061-T6 aluminum assembly, addressing the factory pipes' tendency to become brittle from heat cycling and crack or blow apart under boost. The kit uses mandrel-bent 2.85 inch tubing larger than stock, a black powder-coated finish, a billet CNC throttle body flange, and 4-ply reinforced silicone couplers to safely support higher boost pressure.

Fitment: BMW 1, 2, 3 and 4 Series models on the F20, F22, F30 and F32 platforms equipped with the N55B30 engine.
