Spark plugs? Every 30,000? Oops! I have 69,800 on my truck and still have the stock plugs. Looks like I better change them next weekend. But obviously the stock copper plugs rock because I could probably get another 30,000 out of them. But since I am out of warranty completely in 200 miles it is time to bring her up to par.

 

It's going to be a pain with that monster, best bet would be to lift with a floor jack, remove tires, then drop floor jack so they will be easier to get to.
