Going to install a new blow off valve on your Caliber SRT, Neon SRT, or PT Cruiser GT? You're going to need to install this block off plate to block the factory blow off valve port. This block plate does not come with a gasket, and you will need to use red RTV sealant to seal this piece to the turbo port. Red RTV is easily found at any local auto parts store, and costs a few dollars for a large tube.

(This part is not required for Mopar Performance Blow Off Valve installation).
