saying 'best cheap' is an oxymoron. anyway, id just get autolite 103. they are about $10 for 6. NGK TR55 are a little better, but a little more.

they arent bad to do at all if the factory plug wires arent stuck on the stockers like mine were.

103's are way too cold for a stock car. I think 606's or 605's will work just fine if you want to use autolite. Otherwise go with stock delco's.
