which 2 step colder plugs to use?
Whats the part # for 2 step colder then stock, copper plugs from NGK? I tried to find them on sparkplugs.com but I couldn't. ZFR6F-11 is what I got for stock, but in copper instead of platinum. But there wasn't a ZFR8F-11

What engine are you running? Sounds like a b18b, I am running zfr6f-11, thats one step colder as zfr5f's are stock for me. You may not need two steps colder plugs if you aren't running high hp. I think if you are pushing 50-75 more than stock, one step colder should be fine.
