need help with spark plug.

I've tried a lot of spark plug brands over the years and have always had the best luck with Bosch Platinums, single electrode. NGKs are good but seem to foul easily. Delco, Autolite, and Champion are all cheap and you get what you pay for with those. Hope that helps.
 
Bosch Platinums will foul before any exposed electrode based will. I would install NGK iridium and be good for the next 100,000 miles.
