Blow Off Valve Kit

High performance turbo systems require a BOV when running higher than stock boost pressures.  The reason is turbochargers continue to force air into the charge tubes and intercooler even after you lift off the pedal (which closes the throttle).  Pumping air against a closed throttle super heats the air in the charge tubes and is damaging to the turbocharger bearing system.  Installing a BOV allows this pressure to be released upon the closing of the throttle which increases throttle response in on/off/on throttle conditions by venting the the hot compressed air.
