Turbosmart Kompact Dual Port BOV kit for N54-powered BMWs - built to handle boost without flinching or leaking. Includes two valves, all hoses, clamps, fittings and blanking plugs.
Pink springs pre-fitted (-24 to -14 InHg) for crisp N54 response and stable boost control
Direct bolt-on fit for E82 135i, E90/E92/E93 335i, E60 535i and Z4 35i - N54 engine only
No tuning needed. No plastic OEM compromises. Just louder, more authoritative dump valve sound and zero boost creep
Ideal for fast road or track day use where reliability and feedback matter more than showroom silence.
