That's your best value

I've never heard of a performance plug that actually did anything other than empty your wallet

I worked for a company that tested the various types of plugs; there was basically no difference except for the longer life of the more exotic plugs. If you have a vehicle where it takes a day to change plugs, they are worth it. If not, save your money for your beverage of choice.

But the ones with 7 Palladium-alloy-coated electrodes and diamond powder insulators get 20% better HP on the Dyno's and 30% increased fuel mileage. I SAW IT ON TV, IT MUST BE TRUE!

Everyone keeps telling me that "you get what you pay for", then you say I should put $2 plugs in my bike. Next you're going to tell me that my SpiralMax doesn't work. Some help you are!

What you really need is one of those water softeners that clamp around your pipe. No salt, no electricity, no batteries. They gotta work, it says so on TV!
