Model Number: 223115

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.

    With this pipe and the Freddy style flange, will the RFl BOV be a direct fit?

      We think you mean to ask if the TurboXS RFL will fit with a Greddy flange. If thats the case, the answer is no. The turboxs flange and greddy flanges are radically different.

    Besides the BOV, is this the only kit I would need to buy?

      Correct, in order to mount a aftermarket blow off valve on your car you'd need a mounting solution (this piece will work fine!) and the blow off valve.

    With this upper hard pipe, would any of these flanges fit a turboxs frl? Or would I have to get a different flange?

      No, AGP does not offer a Turboxs flange with this uppipe. So, you cannot install a Turboxs bov without the turboxs flange on the pipe.

    I just bought the Synchronic Diverter valve Upgrade kit for Greddy BOV ( Synapse DV ) from you guys ... Is this up-pipe all I need for installation ? And if so which option should I go for in choosing flange ?

      Correct, you need a mounting pipe to install the blow off valve on your Caliber. You'd need either a Greddy or HKS flange adapter with the Synapse valve and the Greddy or HKS flanged AGP upper hard pipe.
