The Kompact EM blow off valve (BOV) range from Turbosmart is a line of compact, heavy-duty replacements for factory ECU-controlled diverter valves. Kompact EM valves are now available as bolt-on fitments for dozens of OEM applications ranging from Alfa Romeo to VW.
The VR7 style is designed to fit directly in place of the OEM diverter valve on 2013-22 GM performance vehicles with the Gen 3 EcoTec 2.0L LTG turbo gasoline engine (Cadillac ATS, Chevrolet Camaro & Malibu, Buick Regal, Holden Commodore). Simply unplug the factory diverter valve wiring harness and remove the 3 bolts holding it in place, then bolt on the Kompact valve and plug the EM lead into the factory harness. That's it! There's no programming, no adjustment, no learning steps, and no fine-tuning.
This dual-port (external venting) version dumps excess charge air to the atmosphere for an unmistakeable turbo sound. Its robust construction will hold more boost pressure than most OEM valves are designed for, but it will not confuse your ECU or interfere with any of its factory-programmed strategies.
Note 1: Externally-vented blow off valves are generally more active than most OEM diverter valves and are usually much more audible than stock.
Note 2: This product is not designed or sold for use on pollution-controlled vehicles (not CARB excempt for use in CA). It is for competition use only.
