This is our Stage II evacuation kit. The kit is designed to release excess crankcase pressure to atmosphere in forced induction applications. We have tried many different designs until we found what works the best. The kit comes complete with two valve covers.The front valve cover has been drilled 1/2 inch and a #10AN bung welded to the valve cover and then is powder coated customers color of choice. We have supplied a special designed canister to catch oil vapor and let the pressure escape through a top mounted filter. The canister also comes with a bottom drain plug to empty the trapped liquids. To finish it off, the kit also comes complete with mounting bracket, clamp, and black cloth braided hose with crimped on fittings at each end to make the kit clean and simple to install.
