Sparkplug question

alright so im doing my GM and find that some parts need to be replaced one of which is the sparkplugs....now my question is the bosch platinum, platinum 2,or platinum +4s any better than other sparkplugs like auto light or champion...and do more prongs make a differance?

GM = General Maintenance?

I'd go with Champion. After reading a lot of threads here, they generally give the best consistency and performance. There have been several threads where other plugs caused problems.

Having more prongs doesn't necessarily mean it's a better plug. There's a certain amount of voltage going through, and if you disperse that voltage through 2 or more prongs you're maybe making a larger spark area of less intense spark rather than a single area of more intense spark.

I've never had a problem with plain ole one prong Champions.

Yea, by GM i mean General Mantainance

i just did my plugs, cap, rotor & wires wed. used champion sparks. idles like a champ

I would use Champion truck plugs. My brother use to work at the Jeep dealer and he said the same thing. I used Bosch Plats one time and they went bad shortly after.
