What's the correct socket size for nkg plugs? 5/8 don't seem to fit

D8EA spark plugs are 18mm

DPR8EA spark plugs are 16mm

If you bought both a 16 and an 18, that would cover you. But...16mm is very close to 5/8", so perhaps an 18 would be all you need...

Good luck finding an 18mm spark plug socket. Thanks Snap-on guy here's your $50. ;)

But just remember that while all other tools go like this "reet-reet-reet" Snap-ons go like this (silence).

- That's what a Snap-on salesman told me at least.

Try Napa - $4

I got mine from sears, craftsman. Also picked up just a regular 18mm deep socket to hold in my toolbox there
