i just couldn’t figure what the difference from iridium to the regular ones performance wise. I researched and basically came up with the conclusion they are pointless for me in my build. They provide a stronger spark allowing a slightly larger gap but ur better off upgraded your electrical then spending $50 on plugs.

The regular BKR7E’s are copper I believe, they’re good but can’t beat an iridium plug in terms of performance and longevity…

since Iridium runs hotter than copper, it’s good to go 1 - 2 steps colder than the copper plug so BKR7E’s = BKR8E’s (in Iridium V-Power)
