Greetings Everyone!

I decided to install my own new spark plugs and not pay Mazda a mere $185.00 for the job. Anyway, I cannot get the plugs off! I believe I have the wrong size socket for the plugs. I have tried all my plug-sockets and none seem to remove the plugs. Therefore, does anyone know the size of SOCKET that the STANDARD plugs for a 2012 SKYACTIVE Mazda 3 NEEDS?

THANKS,
RICHARD

 

I believe they are 14mm.

Use a 14mm tube socket to fully unscrew them, them either use a extendable magnet to lift them out or use a plastic or rubber tube to jam over the top of the plug to lift them in & out.
