The multiple award-winning Kompact EM Series of upgraded Blow Off Valves is the world's first truly plug-and-play upgrade solution for your factory diverter valve. Unplug and unbolt your OEM valve, and install a Kompact EM valve in its place. No adaptors, hoses, or extra assembly are required.
The Kompact EM Valve Series from Turbosmart takes motorsport-proven billet valve technology and adds an onboard, proprietary solenoid system and internal pressure control channels, resulting in a simple plug-and-play valve with full OE integration and control. There are no reference hoses, no separate solenoids, and no fiddly bits - Just bolt-on and plug in!
You can count on unmatched performance and reliability as a direct replacement for your factory diverter valve. The Kompact EM Valves overcome the common faults associated with plastic factory valves through our Boost-Balance Valve Design (the more boost you have, the better it seals), a positive seal O-ring on the piston's face, and billet construction. No matter your application, the Kompact EM Series will hold more boost and be more responsive in any environment.

Armor Plated wiseco pistons have almost a bronze colored tint to the top of the piston and the wrist pin bore. Wiseco's Armor Plating is an abrasion resistant plating that raises the hardness of the aluminum, increases the durability of the ring grooves, prevents micro-welding of the piston rings, reduces carbon buildup and combats corrosion caused by detonation. Wiseco's most popular pistons now include Armor Plating.
