Bosch Platnium +2 Spark Plugs
Well, these little plugs have a bad rep around this board, so I just want to throw in my two cents.
They are pricey, but so far it's well worth it. They made a world of difference in my truck, idle and acceleration are smoother, and the truck has more power. Installation was as easy as any spark plug, and I didn't even have to gap them!
A+ well worth the money.
