i got a set of ngk iridiums and want to know what to gap them at.

 

dont run them.. get a set of v-powers and run them at around 28..

 

well i already have them is it a big deal to get the v-powers?

 

Not really, but I've never seen anyone with the copper plugs complain that their plug's electrode snapped off, tumbled around in their head, and ruined the entire motor. I've seen a few people with iridiums have that problem though.

When it comes to a turbo Honda:
You'll change more plugs with copper v-power plugs.
You'll change more engines with iridium/platinum plugs.

 

ok ill go with the v-powers then lol. is it just a general measurement of 28 for any plug? and since im not crazy horepower a copper plug wouldnt restrict anthing would it lol

 

also what heat range?

 

How much whp is the application making ?
Standard 220-350 whp applications can run:
#7 Heat Range NGK NGK R5671A-7 NGK-4091 gapped at .028

 

yeah im in that range. so everyone reccommends the v-powers? isnt this like a stock spark plug?

 

Yes and yes, stock is a 6 heat range though iirc...

 

yes 7 heat range BKR7E and gap them down to 26-28 depending if you get spark blow out you can gap them down further if needed. Im currently run my gaps 24 without a hicup
