Catch-can install
 

OK, just installed the catch can. I found a description of the GReddy catch can and this is what it says...

"A catch tank (or can) works just like a crankcase vent filter. It will bypass the connection between the crankcase and the air induction intake track. This will relieve pressure place against the valve train under engine load. But unlike a crankcase vent filter, the oil used by the valve train will not drip onto adjacent engine components. The oil catch tank will ‘catch’ the oil and moisture in the blow-by gas that cause carbon and sludge build-up in the intake system and the engine. This will keep your engine compartment clean, your performance maximized, and give your engine that custom look."

I agree with everything after the last comma in that paragraph.... give your engine that custom look. I'm not noticing anything else. Sure looks pretty though.

Maybe a newb question, but how bad was the install? Also will Mazda warrenty have any issues with it? I cannot see why they would, but I thought I should ask?

Install wasn't too bad, didn't mount where I originally wanted it, but due to the size (height) thats the only place it would fit properly. No warranty issues, already checked.

where did you want to put it originaly...looks pretty sweet right where it is IMO
