Mine have gone over 100k. They are on my list of upcoming maintenance items. I don't tow, but lots of mountain driving since I've had it push the rpm higher than normal.Kestral wrote:Will the stock spark plugs really go 100,000 miles? Should I change them early considering I tow a camper? I am thinking the heat cycles and high rpm when towing would wear them more then normal driving? How do they look at 100k when some of you changed them?
Man I wish my father in law had a cracked manifold so I could hear him coming! .. It would give me time to jump in my Pathfinder and take off before he gets here!disallow wrote:I don't think my Father-in-law has changed the spark plugs in any vehicle he's ever owned. His 89 Toyota Van finally crapped out at 15 years and 420k kms. Ran like a top, other than the cracked manifold that made it so you could hear him coming from about 5 miles away.
Thing had 4wd too.
2008 has the OE Laser Iridiums, so I wouldn't be surprised as they do take a long time to wear out. But at 176,000 miles, I think you got your money's worth out of them!DanJetta wrote:I'm at 176,000 miles with the original spark plugs and it still purrs like a kitten. Going to change them this Spring because I feel like I probably should.
My wife's '03 Explorer still has the original, factory installed plugs at 163,000 miles. I'm tempted to see just how long it will go.DanJetta wrote:I'm at 176,000 miles with the original spark plugs and it still purrs like a kitten.

At this point they may be stuck in the block! I have a friend who is a Ford teck and this is common on Fords. It can be quite difficult and time consuming to remove them also expensive.Homer J wrote:My wife's '03 Explorer still has the original, factory installed plugs at 163,000 miles.
