Hey guys... whats a good sparkplug to get fer me truck... i heard Bosch platinum +4's were good... but i would need a good wire set too.... how much would a good set cost me... oh.. and after wards... how much of a HP boost would it give me.. 2? maybe as much as 10???

oh by the way... those damn sparkplugs are a pain to get out!!!:werd:

the stock plugs are fine.if you just want to replace them to do it i recommend putting in the stock ones. when i pulled my stock ones at like 50k miles they still looked new.not worth changing the to just change them.imo

I tried the Bosch +4 and didnt notice any power difference and my mileage dropped 2 mpg. Ive got Autolites now and they work great.

Depends on your driving style. if you drive around town (stop & go) stay with stock GM plugs & wires. Highway & towing go to a gooler heat range plug & MSD A6 ignition box.
Good Luck
