#8 Spark Plug
I'm just wondering what the consensus is for swapping out the #8 spark plug. I swapped the other 7 in about an hour and a half yesterday and ran out of time. I took out the #4 coil - which really helped. This is my 2nd time in as she has 206,000. I just remember it being a real pain ....
Wife said to take it to a shop, and my thought is that they would have skipped #8.

easiest way that i found (since i have headeres) is to take off the coil pack and just go from the top...

When I had stock headers I had to go from the bottom. I've heard some have had to move the starter out of the way to get to it. #8 is a mofo when you have stock exhaust. Now with LTs I do like Spaz, remove coil pack and go from the top. LTs FTW!

1999 Formula WS6 M6-sold- 2001 Silverado Z71
For me, it was really easy from the top with the coil pack off, intake manifold off, and stock exhaust at the time. I had the intake off for a different reason, but that allowed me to rest right on the engine and get in it there to get it. I'm not suggesting you remove your intake manifold just to do one spark plug, unless you have a good reason to (ie upgrade, chasing a vacuum leak, etc)

Arctic White & Black- '98 WS6 M6 - SWAPTIME!
I usually just deal, remove all the crap from the top, cuss a few times, usually bust a knuckle, then cuss some more and put it back together. It's a lengthy process but it gets the job done.

Sunfire Yellow- 02 Collector Edition T/A
My exhaust is stock and I can do all 8 in less than a hour starting with #8. I've tried both ways and prefer accessing it from underneath. It helps to have long arms.

Just my 02 but i always go from underneath, i slide the spark plug socket on and use a 7/8 rachet wrench to back it out, takes longer to get the car in the air then it does to replace.
J2001 SS, Its not the car its the Driver that matters....
