Default Correct gap for ngk iridum spark plugs???

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
