Radium Engineering Fluid Lock Catch Can Kit - Mazda MX-5 (NA / NB)
The Radium Engineering Fluid Lock catch can kit (SKU 20-0336-FL) is a direct fit for the 1989–2005 Mazda MX-5 (NA / NB). It mounts at the left-hand strut tower near the exhaust manifold using OEM holes, and captures oil mist, fuel vapour and sludge from the crankcase gases before they reach the intake manifold.
The kit includes enough components to plumb the can to either the PCV side or the crankcase (CCV) side of the engine. On the PCV side it runs inline between the PCV valve and intake manifold and keeps the factory function. Radium's Fluid Lock design uses a patented mechanism that stops the reservoir overfilling and holds the collected fluid until it is emptied.
Note: Check the fluid level with the integrated dipstick after 3–4 weeks of driving to work out an emptying interval. For all engine breather ports to be isolated, choose Radium's dual catch can kit. Installation by a professional is recommended.
