Radium Engineering Fluid Lock Dual Catch Can Kit – 89–05 Mazda MX-5

The Radium Engineering 20-0337 Dual Catch Can Kit is a direct-fit solution for 1989–2005 Mazda MX-5 models. This kit addresses both crankcase ventilation (CCV) and positive crankcase ventilation (PCV), capturing oil and fuel vapors before they re-enter the intake system. Ideal for naturally aspirated and forced induction setups, this is the ultimate upgrade for long-term engine health and consistent performance.

Vehicle Compatibility:

• 1989–1997 Mazda MX-5 Miata (NA)

• 1998–2005 Mazda MX-5 Miata (NB)

Overview:
This dual catch can system installs cleanly in the engine bay using factory mounting locations. The CCV catch can filters blow-by gases under wide-open throttle, while the PCV catch can filters contaminants during low-load cruising. Together, they ensure a clean intake path, reduce oil buildup, and lower hydrocarbon emissions. The system retains factory PCV functionality and includes everything needed for a complete install with no permanent modifications.

Key Features:

• Dual sealed catch cans for PCV and CCV systems

• Baffled internal design for superior oil separation

• Fully emissions and track legal

• Helps prevent intake and intercooler contamination

• Promotes consistent engine performance

• Ideal for high-output or forced induction builds
