The factory blow off valve in the Caliber SRT-4 not only vents back into the inlet of the compressor housing, but it also acts as a way to limit boost. Remove the factory installed BOV, and install our block off plate to the compressor housing. Install the aluminum tubing that comes off the compressor housing outlet and attach your new Blow Off Valve. Kit includes tube, silicone hump hose, block off plate, hose clamps, vacuum lines, zip ties, and fittings.

This uppipe is available with a Greddy blow off valve, or the the HKS blow off flange.

This mounting pipe is made out of aluminum and powdercoated in a great black finish.

This kit is now coming with AGP's newest block off plate which has built in rubber O rings.
