I'd like to hear feedback from mishimoto OCCs. TIA.

Any catch can will work, as they simply function to separate the oil blow by vapors from the air. They do this by having baffles to change the air flow direction and thus force the oil out of suspension, and grates to help condense oil along with again trying to drop it out of suspension by allowing the air to flow faster than any oil vapor.

The problem is making those cans fit. IMO the best solution now would be the turner motorsports can, their reverse flow baffle is the best design not only making the air flow reverse direction really forcing that oil to drop out, but it integrates grates as well for even more oil separation. The hoses also sit in a way where water doesn't pool and freeze in the winter. The MMR can imo is not the best designed the baffling is pretty poor, iirc it is just a grate on a hole. The hose design also allows water to pool imo so not the best.


So yeah make sure you not only get a can with good baffling and air flow design otherwise the oil catch can will be essentially just for show and not able to catch anything.
