Was suggested to run these for top end happyiness by a fellow facebooker. See below.
SP63 Valve Cover Breather For Mazda MZR-DISI - SPEED PERF6RMANC3
Who is running and do they have a real point? Not interested in value for money debate (I know expensive), but rather should I be running one on a modded MPS.
All feedback welcome :)
Vents oil/crap to atmosphere instead of recirculating it back into intake...
Probably not REALLY needed... Not at your power level anyways...
Safe for car though? You ever ran one?
Have a look at reedys dual occ setup as an alternative.
Ah, misread what it is... This connects to your oil cap rather than the pcv system like an occ... I've never run one...
Don't think you're pushing enough HP for it to be required
Attachment 17476 Not my engine bay, but here is the guys mounted to the left of the intercooler
Oh, yeah i thought it was a valve cover one too. Unless you are popping your dipstick, I doubt this is needed. Plus pretty sure its illegal if that matters to you.
