Recently bought a 2007 ram with the 4.7L engine, getting ready to do a tuneup but have some questions. I'm gonna be using the champion 439's the truck came with, but is it recommended to use antiseize on the threads? If so, I've heard that antiseize effects the torqueing process, is that true? I was gonna torque them to 20ft lbs? Thanks for all the help

 

Definitely use antiseize. Don't get too caught up in torque specs. Just do snug and a 1/4 turn

 

Alright, which type of antiseize is best for these plugs? I got a tube of permatex aluminum antiseize.

 

Brand does not matter. You are good with what you have.

 

If you can please let's us know the results once you do it. I just got an 08 I'm planning to do it as well. Changing differ. Fluid first. Mine take Bosch FR8TE2 upper. FR8T1332 lower but I'm going with iridium upper and champ. Copper lower

 

Will do, just waiting on my day off.

 

go with the autolite 3923 plugs in the 4.7, they are a step cooler then the factory champions and these motors love them,

 

Super, Ok I will looks like autozone doesn't have them or at least not on their website. I started looking on eBay here's what I found. Does it matter if it's platinum or double platinum.
