Compared to some other cars out there the C5 is simple. That said, if the plug wires haven't been off in a long time they can get fused on and have to be destroyed to get them off. I always keep a spare set of OEM plug wires handly. Anything aftermarket is a waste of money, it's been prooven time and time again.
I don't know I had an oem replacement temporarily and they sucked as far as taking them off. Had em' on for about 500 miles and 1/2 of them ended up having the tip rip out. They also sat kind of loose. I like MSD's if for nothing else they have a solid click feel and stay together when you take them off.

Changing the plugs and wires in the C5 wasn't too bad - at least you can see them. On too many cars you can't even see the wires to know where they run to.
You might have better luck reaching #7 if you lay off the Enzyte for a couple days prior!
I like my car but, not quite that mu... oh wait, yes I do... good call.
actually in response to MSD staying together, FALSE!!!! One of mine exploded in two pieces. So they dont always hold up.
I ordered a set of Mopar Perfs... lets see how those hold up.
for the record, getting the drivers sides out were not as hard as getting them back in for some reason.

I'll do plugs in a C5 ANYDAY...Try changing them in a front wheel drive V6 GM minivan...The front three are a piece of cake....The back three...Well, here's a hint....jack the van up and change them from underneath...and make DAMN sure it's overnight cold!!!
I changed mine a few weeks ago.
I had no major problems.
Took me about an hour at most.
#7 was the hardest but I was able to get it by putting the socket on the plug and then putting the ratchet with extension to it.
I just did the plugs in my C5. A wouderful experience in you're into pain, cuts, and bruses. And old number seven...... I did em all except for number seven. I was scared, my hand was too big, the plug too small. Somebody said to use a socket wrench with a swivel on the head. Two weeks of driving around with seven new plugs and one old one. I finally pucked up the wrench, drank a little courage, and went for it. One and a half hours later I finished. I gotta tell you that my 1986 is way, way easier.
I did mine awhile back and I thought it was pretty easy. Even the #7 wasn't that bad and I didn't even use an extension. Took me 30 minutes with beer breaks. Only thing I moved was the air tube and voila I was gtg.

such as a gen4 f body LS........ number 6 & 8. with a flashlight you can just see the boots and barely touch them with one finger. you have to remove brackets and coil packs to access them. number 7 on a C5 is a piece of cake compared.
