Spark plug change

I have the same socket. I like that it has the springs to grip the plug and no rubber insert to fall out.

Ditto

You should not use anti-seize on NGK spark plugs because they feature a special trivalent plating on the threads, acting as a built-in lubricant and corrosion inhibitor, making anti-seize unnecessary and potentially harmful by causing over-tightening, leading to thread damage, shell stretch, or breakage. NGK plugs are designed to be installed dry to ensure correct torque and heat transfer, preventing serious engine issues like pre-ignition from altered heat ranges or stripped cylinder head threads.

Thanks for the info…
I have a Honda 3kW generator, and was told not to use anti-seize when replacing the NGK spark plug. I am assuming for the same reason.

Has anyone had issues with defective spark plugs? particularly NGK?

Mine misfired. Pulled them out. Gap was off. Put them back in. Gap still wasn't perfect, but enough not to cause a misfire for several months. Then, I started getting a misfire again and eventually, a CEL for cyl. 1 . Mechanic regapped. Ran perfect for maybe 120KM or so before misfires started again.

Replaced them again with pre-gapped Bosch just over a year ago and have not had any issues since.

I bought mine from Amazon, but they did not appear to be knock-offs and had no signs of visual damage on them. I suspect possible damage during shipping.

ditto I paid the Mazda tax...expensive but for me spending on 4 plugs every 40,000 miles is not a big deal...
