Radium Engineering Dual Catch Can Kit with Fluid Lock for 1990-2005 Mazda MX-5 Miata (20-0337-FL)

Fits 1990-2005 Mazda MX-5 Miata (including Mazdaspeed, LS, SE, and Base trims).

The Radium Engineering Dual Catch Can Kit (20-0337-FL) is an essential upgrade for maintaining engine longevity and performance on the NA and NB Mazda Miata. This system provides a comprehensive solution for managing oil blow-by by plumbing into both the PCV (positive crankcase ventilation) line and the crankcase breather line. By capturing oil vapor and moisture before it can enter the intake manifold, the kit prevents carbon buildup on intake valves and helps maintain a consistent fuel octane rating during high-load driving.

Designed for a clean, professional finish, this kit features Radium’s patent-pending Fluid Lock catch cans, which are engineered to effectively separate oil from the air stream while preventing surges. The kit includes vehicle-specific mounting brackets for a direct bolt-in installation that requires no permanent modifications to the chassis.
