Radium Fluid Lock Single Catch Can Kit - Mazda MX-5 NA/NB 89-05

Radium Fluid Lock Single Catch Can Kit - Mazda MX-5 NA/NB 89-05

Application: Mazda MX-5 NA 1989-1997 and NB 1998-2005 (1.6L and 1.8L)
Part Type: Single Fluid Lock catch can kit
Part Number: 20-0336-FL

The Radium Catch Can Kit separates oil and water condensation from the crankcase gases before they reach the intake manifold, throttle body, intake and intercooler. The closed system keeps oil vapour out of the cabin and helps keep the intake clean.

This single-can kit mounts at the left-hand strut tower near the exhaust manifold using OEM holes, and can be plumbed into either the PCV side (inline with the factory PCV valve, which stays functional) or the CCV side. The pressure-sealed can permits intake manifold connection, making it suitable for boosted engines.

Key Features

• Single Can Kit: Plumbs into either the PCV or CCV circuit
• OEM Mounting: Mounts at the LH strut tower using OEM holes
• Fluid Lock Design: Patented Fluid Lock system prevents the reservoir overfilling and holds collected fluid until emptied
• Direct Fitment: Bolts in with no drilling required
• Large Ports: 10AN ORB inlet and outlet ports with a 4AN ORB drain port
• Two-Step Baffling: Two-stage oil separation baffling
• Integrated Dipstick: O-ring sealed dipstick for checking the collected level
• Boost Rated: Pressure-sealed cans permit intake manifold connection on boosted engines

• Radium Fluid Lock catch can (x1)
• Anodised aluminium mounting bracket
• 3/8" PCV hose
• 10AN ORB to 6AN male fitting (x2)

Optional Parts

• Radium Catch Can Petcock Drain Kit (20-0024) – allows the can to be drained without removing the lower reservoir, where there is space underneath

Important Notes

• Suits 1.6L and 1.8L engines
• The OEM air intake box cannot be used with this kit
• There is no fixed emptying interval – check the dipstick from 3–4 weeks of driving and adjust from there; excessive collection can indicate an engine issue such as blow-by, overfilled oil or a PCV valve leaking under load
