Thank you. You have rated this product.

Your Miata isn t running as cleanly as you thought, and this air-oil separator from Moroso is what you need to clean it up. The factory designed the engine to vent excess vapors and oil back into the intake manifold, causing oil deposits that gunk up the intake and the valves, and crankcase vapors which could cause detonation. Plumbing this air-oil separator into the PCV system captures the oil and moisture and contains it in this great looking billet canister.

-Billet Aluminum construction has a raw finish

-Supplied with 3/8", 90 inlet and outlet fittings and 36" of 3/8" rubber hose

-Includes billet aluminum mounting clamp

-Canister unscrews for draining and cleaning

-Moroso name you can trust for great engineering and machining.

BRIAN'S APPLICATION NOTES: This is really for those with RACE built BOOSTED motors. Do not expect any performance gains, that's not what it does....

Thanks for making this work and providing great customer service! I had a full weekend with the install, but man was it worth it. The flywheel was such a good choice. I can't believe how much easier rev-matching down shifts are. The ACT is surprisingly easy to live with, even with the engagement point very low. I'll tackle that when it stops raining. Thanks again for making this happen this weekend.
