4436 Champion truck plugs work great.

 

Never have a come across an engine family as finicky with plugs as our Magnum's are. I have Autolite's in it right now. On my next plug change i may try a set of NGK's. Its really about what the engine likes, as others have already stated. Its not about a "brand" or "performance" name.

 

I used the autolite 3923's and will prolly use them again when needed.

 

If it's any help i wasted $60 bucks on Champions IRIDIUMS and not a C hair of differnce from stock plugs.

 

check out the spark plug sticky !! https://dodgeforum.com/forum/2nd-gen...ark-plugs.html

 

ditto on the autolites. cant speak for other plugs but these work great.

 

Just go with the factory champions, they come in the truck, and are proven to work great with no problems.

 

I had autolite 3924's in my truck and used that to replace them some people put the autolite 3923's in because they are a colder plug.

I trust autolites and will keep using them

 

Another one to look into are the NGK V-power plugs. Thats what I'm currently running.

When they're due, I plan on throwing a set of 3923s in for comparison. Eager to see how they run with the SCT I got now.

 

New guy here.... Just bought an 01 Sport with the 5.2L, and it's about to hit 90k miles. I would like to change out the plugs. I always run oem plugs, from my cars to my toys. Unfortunately in this case it appears to be Champion lol. What is the part number of the factory Champions?
