New MX5 gearbox filler / level plug. Originally this is the plug with the square head on the left side of the gearbox, which after use of incorrect tools often damages the head on this plug.
This version is with hex head which solves the issue - just please use the correct torque to fit back in place.
Regular plug with the square head is available as well.
Fits all MX5 models.
This part has been discontinued by Mazda.
