Did you torque them to spec? Correctly set the gap?

I ran 1 step colder to reduce my NOx levels and because I drive my car hard aka high reving with my new cam, etc. I never experienced carbon fouling ever.
I'm getting stock temp spark plugs right now (pepboys doesn't carry the 1 step cooler plugs). I never experienced broken spark plug tips with the Denso Irridiums I had before, I took those off back when I was getting no spark due to a faulty ignition. so 1 out of 2 sets of the Denso spark plugs I used turned out bad. I'm not wasting money on a 3rd. NGK for now lolz.
They're pre-gapped, I check it and it was at specs. I tighten it, but I never forced them in too tight (no sqeaking or ne sounds)
