Protect you turbo from excess pressure build up.
The Active Autowerke single BOV - Blow Off Valve Kit - sports a huge venturi, designed to handle excess pressure build-up against the turbo compressor impeller blades, 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 safely increase HP and get that cool “whoosh” sound as your BMW 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”
