D16z6 spark pulg Ques.
 

Which brand and type of spark plug should I run with my Tubbo D16Z6 @ 7 lbs of boost? I did a search and they spoke mostly of B series motors. I was told to go with 1 step colder but I am unsure of which brand to use or what gap I should have. Thanks.

I was just searching around for this, I will be picking up a set of zfr6j-11 and gapping them to about .034

ngk, I also came up with this one, zfr6f-11.
Im not sure what the diff is between the two. zfr6j-11
zfr6f-11

they are both one step colder, Im going to ask tomorrow at autozone. They should have these in stock.
