Mishimoto Oil Catch Tank SpecificationsThis oil catch tank gathers heated oil particles. On the majority of standard engines these particles are re-circulated into the intake manifold before being consumed in the combustion chambers reducing emissions. However this can be quite problematic for highly tuned engines : the oil particles can build up over time clogging elements of the air flow system especially intercoolers on turbocharged engines reducing their efficiency. These particles can also increase the engine's operating temperature and the risk of knocking.Keep your engine running smoothly with Mishimoto oil catch cans : the oil particles re-condense in the tank and clean air is released into the atmosphere or the intake manifold (you can choose). Comes with brackets bolts hoses and ties. Installation guide :
