I think they look pretty good for 110K miles on stock plugs NGK PFR5G-11. They're in the order they were pulled.

I'm positive they have 110K. They were changed at 75K by the dealer, I brought them the plugs to have them changed when I had gasket work done. The car has mostly HWY miles, I don't know if that makes a difference?

I have about 127k on my 98. No idea if the provious owner ever changed them. The car runs well but i dont want to replace them if i dont have to. Any input?

i would just to ease your mind, you dont know if the previous owner beat on the car or what everytime i but i new car i change the oil plugs wires etc, and tranny fluid

i wonder if mine look as good as those because i got 122k on my 2002? Haven't taken them out yet because my car still fires up without problems.

You could just pull one of the fronts just to see what shape they're in. It would take about 15 minutes or less. I changed mine mainly because I was doing other work like checking the coils and such. I figured if I was going to do the work to check them I'll do a little more and replace the plugs since they're over 100K while I'm in there.

I do think my car starts better and pulls harder. It definitely doesn't hurt. I got a full set of NGK's Plats. on ebay for $50 shipped. The brown you see on the threads is not rust. It's just discolored anti-seize compound.

im sure ud notice a big difference when u put new ones in lol

Just for future reference, I'd definitely do a tune up to a car that after i purchase it. Unless the person your buying the car from was Jay Leno you don't really know how they took care of it. Besides, it costs like $50 for all the parts

Hayne's manual has a brief summary of spark plug analysis on the back cover. If you do any work to your car, get one (or a Chilton or FSM)

u can change em for peace of mind, but nissan and manufacturer say platinum tipped never have to be changed.

Maxx,

didnt have to change em. but i feel u, why not change em.

mine had looked good too at 150k but I replaced them nonetheless

sonicrunch

What? Really? Can somebody confirm this?

I change mine almost every year. But I drive hard. Plus I get the NGK coppers so it only cost like $ 10-12 for a set of 6. Can't go wrong for that price.
