Best Sparkplugs (Supercharged Mustang)

[Fenrir]

Good Evening Mustang Family!

I first want to say thank you for all the recommendations for on staggered setup tires and went with the Michelin Pilot Sport 4 S.

I have another question which is what sparkplug is the best for a Supercharged Mustang and should I get them pre-gapped?

NGK 6510s at .028. You need to gap them since they come out of the box at .042 gap.

Ford Racing plugs (M-12405-M50A)

The NGK 6510's are good too. I use them.

The only thing with 6510s is out of the box they are like .44 and you need them down to point .28 NGK does not recommend more than .08 max adjustment.

I run Brisk RR12S at .026 gap on E85 and 15lbs of boost - tuner says logs are great. Cars been down the 1/4 mile, 1/2 mile, and regularly raced/driven on the street
