Read Attachment.
I buy the best NGK Mazda racing plugs as they do run the best.
Using two sets which I swap out periodically, they have lasted so long that they end up being cheap.
Each time they are swapped, the pulled ones are cleaned with a spark plug cleaner with low abrasion material, and are re-gapped.
Thus if you think the best plugs are still too expensive, you have the wrong hobby.
