What does the manual state for changing the plugs? How many miles before is what I'm looking for. Thanks

Opps I almost forgot. 2002 3.4

it says at 100,000 to INSPECT the wires and REPLACE the plugs. which that is a long ass time, and im not sure if I believe it. but thats what it says.

Yah... That sound like a long time to me too. I think I'll check it out about 70k or so.. Thanks...

I have the shop manual from HELM for a 2003, says 100K also. I think I am going to change them at 60K anyway.

I changed mine at 60k also. It ran a little better, but it doesn't feel right to let spark plug go for 100k, considering how vital they are and relatively inexpensive to replace.
