Active Autowerke Aluminum Chargepipe Kit w/ BOV – E9X 335i N54

Our single BMW BOV Kit and chargepipe sports a huge venturi, designed to handle excess pressure build-up against the turbo compressor impeller blades, pressure at the impeller to stop spinning (a.k.a. Compressor Surge),which can damage the compressor wheel and shaft. With our BMW 135i 335i Performance BOV in place, the stock turbos are protected as the boost is raised you can take HP to the stratosphere, enjoy the spoils of all that performance, and get that cool whoosh sound as your machine spits out excess inlet pressure.
