I use them in lawn mowers but never in a vehicle.

 

I've been using them. I can't really find a better plug. So any advice is welcome! I thought about iridium TT plugs as they are suppose to increase gas mileage

 

Our trucks really dislike the rare-earth plugs, platinum, iridium, unobtainium, etc..... good for mystery misfires..... A good quality copper plug works best.

 

That's why I went with champion they are holding up so far

 

I hate champion too. I have had too many bad experiences with them....... both in vehicles, and equipment engines.

 

Champion are perfectly fine and the OEM plug. I've used them for all of 240k of my engine except once when the pressure online was to use autolite. Now those were junk. Switched back and doing great. Nothing but copper champs for these old gals.

 

Champion and Autolite are the ones I stay away from. AC delco/NGK and Bosch are my plugs. maybe Accell.

 

I just recently bought this truck and kinda starting to regret it, thought I was getting a deal (which I did I guess) but had the transmission worked on(new governor and solenoid) And still don't want to shift. $400. down the tubes. Dodge is notorious for bad trainnies.

 

I agree with you! My dad and pap all use champions because they said that's all they used on the older cars and they were trusted. So my dad's and paps cars (even the new) get them. I had a misfire on cylinder 5 a while ago and figured it's probably the spark plugs because they had 15,000 miles on them. Pulled them all and they look new, turned out to be a plug wire fell onto the header because the stock wire holders broke..... Now that I think of it I have to find an alternative to them as I never replaced them
Hey I get them for $0.67 a piece

 

Really? Like what?
