With the newest tune or just the v10? I'm ready for my update.

I finally got around to changing my spark plugs to the Livernois .30 issue plugs. Wow what a difference that makes. It's a must with or without a tune. My 2011 Eco stock plugs were gapped all over the place.

Did you do it yourself? How long did the swap take?

Eco, pretty easy to do in the driveway, I asked a million questions on it as I only changed plugs on older cars and truthfully never really looked under the hood of my truck. Instead of thinking about it I just tore into it.

Here's an older post:

OK finished up, took me about an hour as my neighbor was over and we were drinking garage sodas. It would have gone faster if it wasn't so damn hot in my garage and my 2 year old didn't wake up, also watching the nascar truck race on dirt.

I used a 5/8 deep socket with about a 10" extension, and a smaller socket with I think was a 5/16 on it to take the coil bolt off, same as the one used on the battery terminal (I took it off just in case). Use a magnet to pull the plug out. Toughest one was back passenger side because of two large hoses above it (not sure what they were), driver side wasn't bad once you get the oil breather I think it was on the front one and the rear wasn't bad, just a push in pin on the underside of that back pin.

I took longer I think to figure out how the engine cover came off, I am use to them being held on by at least a single bolt or two, it took me a while to realize it was just lifting it off (didn't want to break anything lol).

My plugs were: 2 at 34, a 33, 32, and a 38. Gapped them to 30 the best I could. Runs MUCH smoother at idle, I couldn't believe it. I should have done this a long time ago. And I owe you guys a beer, you were right it is pretty easy to do, not sure why I was worried about it. So easy I should have made a youtube video lol.

I use the stockers and re-gap. They are made by NGK.

Yup stock plugs here too, I would use the stock ones unless they look bad. Otherwise I would go with the stock plugs from a '13, theya re pregapped at .030 in the box, otherwise the ones that are in there should be fine.

Awesome ill be checking them as soon as the heat drops below 110 here lol

Tooke about 45 minutes. Very easy change out. I just bought new ones cuz I had about 45,000 miles on stockers . Just wanted to throw some brand new ones in. And my spark plug wrench has a foam insert so the plug comes right out stuck in the socket. No magnet necessary:-)
