This is the first time I'm changing plugs since I've modded the truck, and I don't know how to read plugs. Truck has a 4 lb lower with an email tune. About 15,000 miles on the plugs. Driver's side on the right.
Thanks

+1, not bad at all for 15k miles. None of them are burnt nor have the tips turned white. How long did it take you to change them???
i just did mine and they look almost exactly the same + i had about 35k on them. they were the iradiums.
