MX-5 Engine Core Plug

Engine freeze plug for Mazda MX-5. Used to blank the engine water outlets, for example if you decide to remove the front coolant neck during coolant reroute.

For reroute you’ll need 30 mm size and we strongly recommend to use with our securing plate for a proper seal. For 1.6 NA (Mk1) with stock ECU we recommend to use only this plate (click to open) which has a threaded hole to retain the fan switch.

Fits all cars from 1989 until 2005 (NA – NB – NBFL).

Shipping world-wide.
