I bought some bosch plugs for my 98 GMC jimmy V6. I've been reading around here that AC Delco's are better. Whats so bad about the bosch??? Should I return them and get the Delcos?

Also plug wires. What brand do you gear heads reccomend?

Thank you in advance.:icon16:

Do a search on spark plugs and go from there. Everyone has a different opinion on the wires but the majority of people here do recommend Delco plugs just because they match up better with our trucks.

But like I said do a search and read some of the posts and make your choice from there.

If you love your blazer do not even let a bosch plug within a mile of it.
The only good place for them is in the trash can.
They will not run right or very long in a GM engine.
Fire up that search engine and check around.
Take them back and tell them you want the AC-delco spark plugs that the good book calls for.
As far as plug wires get the best ones.
When the ask you if you want cheap or a little better or the best tell them you want the best and the one that meets OEM quality specs.
