i just ordered them and i have no performance mods, got them for stock range from zzperformance.com and wondering if anyone has anything good/bad to say about these plugs before i install them??

No stock plugs are PFR6T-10G, they are laser platinum, not iridiums.

jmc is correct, platinum and n20 do not mix, so i had to change them
