Upgrade your vehicle's stock, plastic blow off valve to an aluminum Tial Q Blow Off Valve. By upgrading to a Tial Q BOV your car will be able to hold higher boost levels. It is available in 5 different colors; black, silver, red, blue, purple. Through countless hours of research and development Tial was able to make the same size valve flow 60% more, making this blow off valve the highest flowing on the market.
Please note to install the Tial Blow Off Valve on your vehicle you need the upper intercooler pipe. This pipe is supplied with the Standard and Full Evolution Racewerks Intercooler Kit. If you have or plan to order either the standard or full kit you do not need to purchase the upper intercooler pipe.
