hey guys, i just installed a zex nitrous kit a few weeks ago and was wondering what plugs i should go with, or stay with the same ones i currentley have(ngk 2668) bkr8eix. i have seen the copper plugs that come pregapped to .044 already but are copper. i dont really understand the differnece as far s performance levels between the two plugs.

mod list
aem v2, plm header, test pipe, t1r v3 single. giles preloaded emange tune, zex 75 wet shot. currently running ngk 2668 pregapped to .040. thanks in advance. also where are the cheapest place to get either of these plugs at?

 

i'd stay with the ones you already have. No need to gap or re-gap them. As far as the cheapest prices, I'd 'google-shopping' search the part # and sort by price

 

Okay thanks. I'll just order a new set of those plugs.

 

Are those a step colder?
