NGKIridium IX DCPR7EIX Spark Plugs for 1999-2016 Harley Davidson Twin Cam (Pair)

Q: Should I gap to my owners manual spec or are they designed to work with the smaller pre-gap they came with?

Harley Davidson recommends 0.40" gap. As to "You should never gap an iridium plug", NGK's website states for Harley Davidson, these should be gapped at 0.40". I've found many websites stating that if re-gap is needed use care not to damage the electrode or the porcelain center. So, it's not that you should not re-gap, it's that you should be extremely careful.

Q: Is this 6r12, if so why does it not say so ?

Because these plugs are IX DCPR7EIX 99 TO 16 HARLEY-DAVIDSON
