Just changed my plugs today. Not sure what the gripe over #8 is. I had it out in about 15 minutes. Undid the ground cable and the wire harness that goes over it. Removed the PCV valve connection at the oil fill tube and used a 6" extention and a rachett that has a pivot head on it. When I had it out, I was wondering WTF, that was to easy.....

you described the gripe - plus not being able to really see in there without a mirror to make sure you clean it out before pulling the plug up

yeah no biggie, but still not as easy as the front 6 .... but i'll trade the extra effort every 30k miles for the extra power anyday

Exactly, You just need the right tools. I use my snap-on swivel plug socket > 3" extension, swivel > 8" extension.

that's what I do, get the one most likely to aggravate you over with then the rest is just "one on one time" with your engine

did mine a while ago. Greasing up the O ring on the coil sleeve will help in future.
I replaced the stock with Iridium tipped plugs, so unless there is a problem I don't intend taking them out again.
#8 is a beatch, but I hope never to remove it again.

You need the correct plugs, otherwise damage can occur.

HOLY CR@P I did 4 of mine today. Thanks to Oreily's giving me the wrong plugs and having to run back to the store to get the right one's. But mine came right out no problem. When you put them back use dielectric grease. It helps going back in and coming out the next time.

LOL LOL

Tks for the laugh. I always thought I was the only one that had these problems.

Your new plugs appear to stick further into the cylinder than your old ones.
