Catch Can For JL 3.6L V6 Pentastar by Mishimoto

Mishimoto shares their R&D process and details behind their catch can for the Jeep JL 3.6L V6 Pentastar engine.

What does a catch can do? In short, it combats the effects of blow-by. Blow-by occurs when the explosion that occurs in your engine’s combustion chamber causes fuel, air and moisture to be forced past the rings into the crankcase. By intercepting the blow-by gasses, a catch can filters out the oil, fuel, water and other contaminates from the blow-by gasses, allowing only clean air to return to the cylinders. This keeps an engine running efficiently.
