Moroso air/oil separator kit

Your crankcase is full of oil mist. If that gets into your intake via the PCV system, you`ll find yourself burning oil. Not only is it uncool to have blue smoke coming out of your tailpipe, oil is also very low octane so it can mean a loss in power. Mazda knows this, it`s why they put an oil separator on the 2004-05 Mazdaspeed. Unfortunately, it`s harder to make a good oil separator than you might think and there`s a lot of misinformation out there on how to plumb them in correctly.

Moroso knows, though. Their separator has a tight steel mesh to encourage the oil to drop out of suspension, and it collects in the lower half. The separator can easily be drained via a valve on the bottom. Includes all fittings to install on a Miata.

Currently for non-ABS 1990-97 models, but other applications will be available very soon. The separator is the same, but the brackets will be different.
