The Cusco oil catch tank for Mazda Miata NA6 and NA8 is specified for models listed as 'AFTER M/C' and collects crankcase vapors to reduce oil migration into the intake. Intended for post–mid-cycle NA6/NA8 applications, it helps keep intake plumbing cleaner and supports steadier engine performance with less carbon and oil buildup over time.
