Question:

Seems to me that you should install new once you’ve gone to all the aggravation to remove them.  I always use anti-sieze just for insurance.  I also use dielectric grease on the boots. – Hide quoted text — Show quoted text ->2000 Explorer Limited now has about 42000 miles.  The spark plugs should >last 100000, according to maintenance schedule. >I have seen sites that recommend removing plugs, then reinstalling,  well >before 100000 miles to prevent a difficult removal when the mileage gets to >100000. >Is this really necessary?  Is it advisable to use anti-seize when installing >the spark plugs? >2000 Limited 4X2, 42000 miles >5.0 V8 >most power options >Thanks

2000 Explorer Limited now has about 42000 miles.  The spark plugs should last 100000, according to maintenance schedule. I have seen sites that recommend removing plugs, then reinstalling,  well before 100000 miles to prevent a difficult removal when the mileage gets to 100000. Is this really necessary?  Is it advisable to use anti-seize when installing the spark plugs? 2000 Limited 4X2, 42000 miles 5.0 V8 most power options Thanks

Response:

You should remove and re-gap, then re-install.  (IF they’re in good condition) I just replaced mine at 60k (plug miles, not vehicle miles), A/C Delco plugs.  They were in good condition, no evidence of damage, burning oil, running too rich/lean, the gap was about double spec, but I replace them anyway since I have them out.   Replaced ‘em with Bosch Platinum, just to see how they perform… You really don’t need anti sieze if you put them in snugly with your ratchet and not over tighten. r/ -IanCT

As I have stated before, we have a 1998 Isuzu Trooper (mix of more highway than town driving) and when I pulled the NGK platinum plugs at 85,000 miles, they looked to be in excellent condition.  The recommended interval was 100,000 miles from the factory.  As soon as I borrow my friend’s digital camera, I will take a snap of them and post it. So, with a recommended 105,000 mile interval, that means you have platinum plugs.  You can change them earlier if you desire; it won’t hurt a thing, but I am not sure you are going to gain anything by doing it. – — Curtis Newton http://surf.to/cnewton <delete remove-me. to respond to email> ICQ: 4899169

Personally, i’d change them at about 60k miles. They probably don’t need it, but I’d be afraid they would be corroded to the head if I waited any longer. — To Email me, change snot to hot

Response:

Your car must have platinum tipped plugs, which last much longer than conventional plugs. What’s the point changing them sooner than the recommended interval? On my 99 Accord the recommended replacement interval is 30K, and that is when I change them. There is a small improvement in smoothness with the new plugs, but that is all. The engine starts just as effortlessly, and there’s no change in gas mileage.  So save your money (platinum plugs are expensive.)
