I have 50,000 miles on my 05 Altima. The service manager and the manual say that the spark plugs do not need to be changed till 100,000 miles. Is it really true that they can last that long? Has anybody changed them before 100,000 miles?

The newer iridium plugs can last over 100K.
If you pull them out, the won't look worn at all compared to the older style spark plugs. They should easily last 100K

Yes. Platuim and Iridium Spark plugs can last that long. The reason is that the metal is so hard that it doesn't wear away like the old resistor plugs do. Plus they conduct electricity better than the resistor plugs do which are made of carbon.
If you want to change them sooner that is fine, but is not required. The service schedule is for maximum life of servicable parts. And is a guild for maximum life of the car.
Anything you do to improve the maintanance will extent the life that much more.
You will have part failures for time to time due to the poor manufacturing or normal wear and tear over time, but maintanance will catch these before it becomes serious and expensive problem.

The plugs will be fine the problem we find is a lot of the time the spark plug wont come out. I suggest to replace at 60k just for that reason, and have anti-seize on the threads and then dielectric grease to the spark plug boot to keep moisture and water out, also ads to boot removal next time.

analyse with me ok? the metals that make up the electrode, and jump point places in a spark plug, melt and ware down,do to the detonations in the cylenders. with two years of driving, the spark gap has gotten bigger, the coil pack has to generate more voltages, to fire at that increased gap size.
I would say personaly, every two years requardless the amount of driving, change the plugs and wires. No matter what others may think, a coil pack lasts longer, if it does not need to generate stronger voltages, to fire at decaying spark gaps.

they might used a high quality, long lasting plugs. There are some plug that can last even more than that. They are too expensive though.

The newer plugs can last that long. I'd change them sooner though.
