Agency Power Adj. Blow Off Valve Subaru WRX 02-07 STI 04+ by FEZTEC

It was only a matter of time before Agency Power would release their exclusive line of Blow Off Valves for the Subaru WRX and STI vehicles. From the time of its inception to the USA, the WRX and now STI have required one important piece? The blow off valve is a device that helps relieve pressure between shifts. This keeps the turbo spooled and reduces turbo lag as you go through the gears. In addition, the blow off valve provides that great whoosh sound turbo cars should have that is so desired.

What makes the Agency Power Blow Off Valve above all others? The AP BOV is made in the USA and designed from the bottom up after analyzing the current market competitors. What we designed was a full T6061 CNC aluminum valve. The sleek body has a smooth round surface anodized with rich stylish colors. The Agency Power text is engraved on the body next to the return plate. The horn is removable and has 3 slash cuts to assist with its LOUD sound. The base is designed to use the factory gasket and sit flush will the factory top mount intercooler and all aftermarket front and top mount intercoolers. The brass nipple on the side is ridged to ensure the vacuum hose stays secure and has no leaks. Continuing with style, the top of the valve has the trademark AP logo engraved on the triangle style top which adjusts the valves spring load. This is held in place by a diamond cut lock ring and O ring. The inside of the valve is operated with a piston and steel spring. The spring rate is manufactured to the correct rate for stock to aggressive boost levels. T HERE is O rings inside to provide proper movement and sealing.

The Agency Power BOV is a fully adjustable, fully rebuild able, and a completely useful device. The BOV is designed to be used with several different setups. The valve can be set up to vent 100% to the atmosp HERE or 50/50. This is w HERE 50% of the air is returned to the intake pipe and 50% is vented out. The valve includes the return line plug as well. We recommend this valve for daily drivers to high boost race cars.
