My '10 Frontier is almost at 6 years and 100,000 miles (5 years 9 months and 99,600 miles).
It's time to start thinking about spark plugs. Of course, it comes with NGK Laser Iridiums from the factory. Do I really need to put those exact plugs back into the 4.0L? I can get Autolite XP Iridiums for less than 1/2 the price locally that I would have to order the NGK's from RA but they are still double the price and I have to wait a week to get them.
Both are iridium plugs, the Autolites even have a lifetime warranty. I've always heard Japanese plugs in Japanese cars, but I've never owned a car long enough to have to change the plugs, and that logic just seems kind of silly to me when I think about it. Isn't an iridium plug an iridium plug? Please educate me if I'm way off here.
Thanks!
