N54 Gapping on NGK Laser Iridium Plugs

BoominBimmer · 05-03-2017, 02:11 PM

Getting ready to do my 50k plug swap out on my 335is. Anyone have experience gapping the NGK Laser Iridium plugs? I am seeing .022 and .02. Does it really matter that much?

Thanks!

As far as I know the Iridium plugs cannot be gapped because the material is not pliable. So if they say it's a match, it's a match as-is.

.022 is fine for most applications. Higher boost tunes can go down to .018 - .02
