STANDARD GRADE PLUGS ARE RATED AT 6 THESE PLUGS ARE
ONE GRADE COOLER AT GRADE 7WHICH WILL BE ENOUGH FOR MODS SUPPORTING UP TO 355 BHP



I thought it was the other way round?

Im running 16PSI, would these be fine for my MR2 rev1?

I understand that i can get BKR6e's for cheaper but these last a lot longer

Thanks
