Radium Engineering Catch Can Kit – 1998–2005 Mazda MX-5

Radium Engineering developed the Catch Can Kit for 1998–2005 Mazda MX-5 around the needs of modified street and competition cars, where component compatibility and clean system layout matter as much as outright capacity.

Why This Upgrade Matters

A properly engineered catch-can system intercepts oil mist, fuel vapor and moisture carried through the crankcase ventilation circuit before those contaminants are routed back into the induction system. That matters even more on cars that see sustained RPM, boost, long track sessions or frequent high-load operation.

Product-Specific Details

Dual catch can kit for NB Mazda Miata. One catch can interfaces with the PCV line, the other interfaces with the crankcase vent line. Located clear of popular turbo kit conversions.

Fitment & Application

Application: 1998–2005 Mazda MX-5
Fitment style: Application-Specific

Choose Your Configuration

• Catch Can Setup: Dual — RAD20-1338-FL: Combines the available crankcase-ventilation circuits for the most complete oil-vapor control.
• Catch Can Setup: Single — RAD20-1336-FL

Technical Notes

Radium' current Fluid Lock catch-can architecture uses sealed aluminum construction, internal oil separation and an integrated service/check strategy. Because crankcase layouts vary by engine, the correct PCV, CCV or dual arrangement should be chosen for the specific ventilation path rather than by price alone.

Enthusiast Notes

For an enthusiast car that sees canyon runs, HPDE or forced induction, this is primarily an engine-cleanliness and consistency modification. Service the can regularly and use the collected fluid as another data point when monitoring engine condition.

Before Ordering

Confirm model year, engine, left-/right-hand-drive requirements where applicable, and whether the selected configuration is PCV, CCV or Dual. Review hose routing around aftermarket intake, supercharger or turbo hardware before ordering.
