For my 2000 civic ex, my factory gap is .040! I'm putting new plugs tomorrow and the ones im using (ngk iridums) are gapped at .044! Is it ok to put them in at .044 or re-gap them to .040? I'm running a stock ex!

Thanks in advance!

click iridium


when i got my iridium they were +/- 2 from .044
i gapped it to .044 on all of them. i would definitely gap them to factory specs

 

you have to be insanely careful gapping iridium plugs, you can break the tips real easy.

hate gapping plugs. Champion makes a good tool to gap plugs. the rest i haven't had much luck with.

 

if u fck up the tip gapping it return it to the autoparts store and go to the next closes one!
