Speak softly. And carry a humongous BOV

OK. So here’s the lowdown: BMW builds this incredible go-bot called the 335i,however, you’re not content with merely “incredible”. You’re chasing “stupendous”; and we at Active Autowerke can fulfill all your dreams and more.

Our single BOV 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 valve 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.

All hardware & fittings have that quality factory look you demand, and are built to perform flawlessly under the most aggressive boost conditions.
