Turbosmart BOV Smart Port Dual Port Mitsubishi Evo 4 Through X - Black

The Smart Port is an innovative Blow Off Valve combining advanced design with precision CNC machined billet components. The valve works using two staged ports and a one-way valve on the trumpet outlet. This enables the Smart Port BOV to work like both a bypass AND vent to atmosphere valve in one while also eliminating stalling and significantly reducing the chances of low-speed compressor surge. In addition, the Smart Port's unique lightweight piston is made from aerospace alloy with a military-spec coating, resulting in quicker valve response, better sealing and superior durability.

Additional Information

Our latest Type 5 Dual Port BOV made specifically for the EVO 4 through X features the innovative new Smart Port drive-by-wire friendly staging technology that gives you the response of a plumb-back valve.
