Air/Oil Separator Small Miata 90-05 w/o ABS

The MOROSO Air/Oil Separator Small Miata 90-05 w/o ABS is designed specifically for Mazda Miata enthusiasts seeking efficient crankcase ventilation during spirited driving. This aluminum separator effectively eliminates oil carryover from the PCV system, safeguarding your engine and minimizing carbon deposits in the intake manifold.

With a compact design that measures 7.4 inches in height and a 2.125-inch diameter chamber, this separator utilizes gravity and centrifugal force to capture oil mist before it enters the intake tract. Its polished aluminum construction not only ensures durability but also enhances the aesthetic of your engine bay. The 3/8-inch NPT female inlet and outlet connections facilitate easy integration into both stock and modified PCV lines.

This kit is compatible with 1990–2005 Mazda Miata models without ABS and fits seamlessly into the engine bay without requiring modifications to core components. Whether you're a serious Miata builder or a daily driver, this separator helps maintain valve cleanliness and reduces oil consumption, especially during high-boost applications or extended track sessions.
