Speak softly. And carry a humongous BOV OK. So heres the situation: BMW builds this incredible go-bot called the 335i. But youre not content with merely incredible. Youre chasing stupendous. And your friends at Active Autowerke have just the ticket to help you get there. Our single BOV sports a huge venturi, designed to handle excess pressure build-up against the turbo compressor impeller blades. That pressure can cause 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. Key Features High-efficiency single displacement BOV takes place of two smaller plastic valves Large opening can handle maximum boost, provide high flow Proven and tested to handle 600+ HP All aluminum venturi design with factory-style throttle clamp CNC machined flange Durable black powder-coated wrinkle finish Illustrated instruction manual & installation guide for easy Plug n Play
