Howdy! What is the best place to get spark plugs for the cheapest price? From what i understand, weren't the ones from the factory iridium? Isn't this the best for reliability and all around the best type of plug as opposed to bosch and crappy champion? Lazy question, what should they be gapped to? What other input do you have on plugs? Thanks! -Karl

I use NGK TR55's gapped at .055. They are copper plugs.

Here's a good write-up.
