The Kompact EM series Blow-Off Valves are designed for easy installation as the first truly plug-and-play option available. Simply unplug and unbolt your OEM Blow-Off Valve, and replace it with the Kompact EM without the need for adaptors, hoses, or additional assembly. This product maintains complete OE control of the BOV’s operation while featuring a Dual Port design that vents both to the atmosphere and back into the air intake.
