We designed this to fill the gap between stock style and aftermarket intakes that have no provision or easy way to incorporate a PCV into your crankcase/catch can system. Benefits of this is to keep a correct flow to the crankcase as well as not giving engine to much air making idle tuning difficult. This block accepts a stock 6.4 PCV which you can remove from a stock intake, or we have new Mopar units available. The PCV Block has 8AN ORB ports for easy fitting integration with AN line catch can systems and socket cap style mount for a flush clean look that accepts either 1/4 or 6mm bolts.
