Hey guys i got this as part of a deal with my 60's and 2.8 they're the ngk 2 step colder plugs...should i ditch them and go with one step colder ? or should i just install them ? either way its a zzp kit with the zzp tune, i believe they mentioned a .035 gap for them does this apply for the 2 step colder ones ? Worse comes to worse i'll call them and ask

Thanks

One step colder would be better for your setup. 2 steps colder is a little much.
