where is a good place to get the one step colder plugs for a good price?
also with a 75 shot wet kit i should use copper pluges right? and what should be the gapping?

 

i accually got my one step colder plugs at the nissan dealer for like 1$ a piece

 

you can get them from napa the ngk part number i is BKR6E-11....i dont know the gap i left it the way the plugs where which is .044....i have the equivalent to these which are the denso plugs....but if you want the ngk thats the part number for one step colder and BKR7E-11 would be 2 steps colder....

 

I hear some people are having good luck with Iridium.

And I think they should be gapped to .037
