Turbosmart 15-18 Mercedes-Benz C63 LHS BOV Kompact EM Plumb Back VR33 BOV (Single BOV)

The Turbosmart Kompact EM Plumb Back Blow-Off Valve uses a unique billet aluminum construction, machined from a solid block. This isn't a flimsy plastic part; it's built to handle the pressures and temperatures found in a performance turbocharged engine. Specifically designed for the 2015-2018 Mercedes-Benz C63 AMG with the VR33 engine, this valve recirculates all discharged air back into the intake system, meaning you won't hear the typical 'pssh' sound. This plumb-back design is often chosen for its stealthy operation and to maintain proper air-fuel ratios by keeping the recirculated air within the factory ECU's calculations.

This Kompact EM model is a direct-fit replacement for your factory blow-off valve, making installation straightforward without needing any welding or major modifications. The internal diaphragm is specifically tuned to hold boost pressure effectively, preventing compressor surge when you lift off the throttle. This helps protect your turbocharger and ensures consistent boost delivery for improved throttle response. The solid billet construction means it's well-built to last, resisting leaks and maintaining its performance over time.
