I got my plugs on and checking the gap with feeler gauge reads .027 which is like .068 mm. Spec is .08mm.

I thought they should be correct out of the box as I have read older posts.

What gives. Also regapping on these plugs can damage them, right? Did you guys run them as is?

Pre gapped to what? We're they checked?

Regap plugs is something totally unknown in europe, so if those plugs are meant to be used in the M113 engines, i would just leave the gap the way they came out of the box.

No I just kinda compared the gap with my stock plugs by looks wise. I installed them my self so I was the only one to check them. Never had an issue, car always ran and runs as smooth as it gets.

iridium plugs are gapped from factory - not needed, unless you drop one
