I changed them at 90K back in 2010, and today at 237K... Sheesh, I remembered now why I've put it of for so long..PITA...The gaps averaged .075 (should be .045)..

 

It's not a walk in the park. It's way easier on my 300C.

 

I have no problems saying that I'll pay someone to change the spark plugs in this truck.

 

I feel your pain. I changed mine today at 45K miles on my 07 Ram 4X4 with the 5.7 engine. It has been 5 years since I changed them at 43K.
I almost forgot what a pain it is to get to the back right #8 plug with the hoses in the way. In fact the dreaded #5 and #7 that is under the brake booster is easier to change than the #8 plug. All I used was a 3/8" drive plug socket with a rubber insert, two 3" extensions , 10mm socket, and a ratchet wrench.
With that said, It was a whole lot easier that the transmission filter and fluid change I did yesterday,

 

I find the tranny filter/fluid change easy, just a little messy.

 

What's the going rate??

It's easier to change plugs in a 440 A-body than these.
