whenever you change spark plugs dont put bosch plugs in them. they are terrible. i put them in my z71 and it skipped and sputtered. so stay with the original ac plugs....

 

Many delco plugs are bosch...but not for a p/u

 

i put bosch platinum/irridium fusions in mine and it idles real nice... then again, for 90 freakin dollars i wanted it to shoot fire out the tips

 

LOL! Your like me, you add some octane boost and expect it to start idleing like a top fuel dragster.

 

Argon what plugs do you recommend? How often do you recommend changing them? I know autozone told me the iridiums only have to be changed every 100,000 but that sounds a little off to me.

 

yeah,100 k on a GEN 3 engine (4.8,,,5,3,,,6.0)..I'd use what came in it...vast research was done to put the perfect plug in

 

Guys I wouldn't reccomend any aftermarket plug and in your veh. Delco makes some good equipment and ive seen nothing but problems with the bosch platinum CRAP!!! They junk out on every veh ive seen put in. Chevy, Ford, Dodge.....bosch SUCK

 

man, i love flame throwers, got em on a few of my cars, just an absolutevulgar display of power.............sorry the flame out the exhaust comment got me side tracked

 

Anyone have an opinion on Denso spark plugs?

 

I just put Bosch plugs in my Grand Prix and they work nicely. Got good reccomendations from the auto parts store on them and I trust him (relatively). Are you saying I should pull them out of the car, stomp them on the ground, and get new ones?
