Good as Gold

I bought these for my 2013 3.5 ecoboost and gapped then at .0275 They worked amazing I have a few mods and a custom tune and I live in hot west Texas I am pretty sure the one step colder was a great addition. They say the rule is for every 100hp you add you need to go one step colder. I have about 70 hp over stock and I run them and thought they worked great. I will definitely buy them again.
