Our single BMW BOV Kit 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.
All hardware & fittings have that quality factory look you demand, and are built to perform flawlessly under the most aggressive boost conditions. Combine with our effective BMW Software for the ultimate performance tandem. Designed, and made by BMW tuner, Active Autowerke to help you "...Come Play with POWER..."
