Ok i kno i could search to find but i use my phone to use tha forum so i called the parts store to get new plugs and they said that autolites 3923 doesnt go in my truck itll work but thats not what it calls for ... what plug do i need optimal performance ? i havnt done any upgrades latley my sig is up to date and whats the deal on platinum plugs i need to do this right and tomorrow night so... thanx guys jay

 

I along with several others have had bad luck with the Autolites. The ran good for a month or so then just made a noise like it was missing somewhat. So I put the stock Champions in. I recommend those. I am now running the Platinum Champions and like them too.

I just didn't like the Autolites. Some do and some don't.

 

just tryn to get some opinions and weigh out my options it sounds like its missn now but they all fire and are shot

 

champions are factory replacement but i don't care for them autolite's i've also haven't had any luck with iether i'm using ngk's now for the past 30,000 miles and my truck loves them they are a excellent heat range plug

 

after doin a lil lookn i got ngk v power and put them in tonight well see how they do...j
