Designed for the DIY installers, the universal APR Catch Can System Block Off Plate is designed for use on vehicles where APR does not sell an application specific Catch Can System. The APR Oil Catch Can System traps excessive crankcase oil vapors and gunk from entering the engine. This helps to reduce carbon buildup on intake valves, octane lowering oil vapors and oil pooling in the intake tract. This plate is used to replace the PCV and adapt a can in any configuration you can dream up.
