Engine freeze plug for Mazda MX-5. Used to blank the engine head outlet if you decide to remove the front coolant neck during coolant reroute.
We strongly recommend to use with a securing plate for proper seal. For 1.6 NA (Mk1) with stock ECU we recommend to use only the blanking plate (separate listing) which has a threaded hole to retain the fan switch.
Fits all cars from 1989 until 2005 (NA – NB – NBFL).
