      Must set the gap

      Gap must be set on these. Came in about .020-.030 different from stock gap. Fit well and seemed to be good quality. But had issues with coils so didn’t end up using these. Will be returning. Returning plugs and coils.

      Spark plug review

      Worked great for my application as the previous plugs had 131,000 miles on them. My truck runs much smoother and better on gas as well.

      Fixed misfire on custom tune

      These plugs came gapped a little tight. I would definitely recommend checking before installing. I gapped them at .045. When I pulled the stock plugs they were all nearly at .060 after 98k miles. Did I what I hoping for, fixed my random misfire on cylinder 2 on my MPT custom e85 tune under WOT. There were no misfires on the stock tune. I have some bolt-ons: S&B intake, BBK 85mm throttle body, BBK long tube headers, BBK high flow cats, Borla S-Type cat back, BDX tuner with custom E85 PRX tune by MPT tuning. Arrived next day, looks like they had this in stock in my city. Coils are arriving today, should be good to go for awhile now hopefully.
