The Cusco oil catch can for Mazda RX-7 (FC3S) is a dedicated crankcase ventilation accessory that captures oil and contaminants before they re-enter the intake. Built for this rotary application, the catch can helps keep intake tract and combustion chambers cleaner, supporting consistent engine performance and simplifying maintenance in boosted or high-mileage setups where oil blow-by is a concern.
