I am a bit confused. When refering to "plugs" as being "copper", ... all plugs, including Iridium, have copper cores, OR at least I thought they did. I know what everyone is refering to as plain copper plugs as the "normal" every day general purpose inexpensive plugs. I guess it's time for me to contact NGK, Champion and a couple other plug makers and get the straight poop on all the chatter about plugs for our vehicles. Has anyone done this yet?
One point I saw on here was someone that was setting their plugs to the widest recommended gap. From what I know and have read, thats a bad idea. As the plugs fire, small amounts of material are either transfered or eroded away eventually making the gap wider. Just check your old plugs when you take them out. You will find that the gap is wider than what you set them at when you installed them. So, following this, shouldn't you set your gap to the smallest recommended gap? I do.

As far as changing the plugs in the back all you need is a universal and a six inch extension. It is alot easier to take off the (forget the proper name) part where the intake is. Hell with the dealer if you dont HAVE to.Changed mine and the power was back in the throttle.Didnt change plug wires,have 175 k on them, GOOD LUCK took me about 4hrs. Bought the stock champion plugs,was told it makes no differance in anything unless you change wires,coil packs (had to change one of mine,$40)etc... would be costly.

I changed my plugs yesterday. Took about 2.5 hours. The one's in the back look like a pain...but they were'nt that bad. I used a plug socket, 3" ext and a swivel. Had to piece them on and off but it worked pretty slick. Truck has 49,200 on the plugs and they didn't look the worse, so I agree with being able to roll 50K.

Copper plugs fire a bit hotter than other metals. Copper is a better conductor of electricity. The exotic metals, such as platinum or iridium, have more resistance in them (thus weaker spark) but will last longer. it's a trade-off. The 09-up use a different plug (same coils though) that is not copper or Platinum. They are actually nickle.

Copper plugs are cheap and I will continue to use the NGK's or Champions. I got my NGK's for $45 shipped to my door last time. another 10K and I'll change them again.
