is there anything i need to know that's unique to a C5 corvette about changing the plugs? Special tools needed?
thanks.
thanks.
Swivel ended 5/8 spark plug socket, short 3" extension, 5"-6" extension, ratchet wrench. Careful pulling the spark plug wires off the spark plugs. Slow and easy, and from what I've heard # 7 (all the way back on the drivers side) is the only tough spark plug to get out and in. I haven't done mine yet, but will change plug wires when I change plugs.

Start with the right tools, I learned the hard way. I still can see scars of my sparkplug job from last year on my arm.
It really does not need to be replaced often. GM recommends 100K miles and there is a reason for that.
But then again, it's a learning experience and good measure. I really cant believe those things last 100k miles.

Actually, you can get 7 of them done in about 10 minutes. The closest one to the firewall on the drivers side (#7 I think) will take the rest of the day

I did it at 50K I don't plan to ever do it again with the 100K plugs I put in.
Here's a tip, wear some gloves...
I used the "racing" type gloves for my motorcycle. Helped alot of the knuckle scrapping, but did make it harder to fit your hand in hard-to-reach areas...
Another thing I done was crack one or two of the plugs as I was putting them in. Made the car idle/run horribly, I couldn't figure out what it was. Luckily, the forum pointed me in the right direction and I got everything squared away.
Just take your time and be patient about it! Yes, the four letter word is mandatory!

I did hear that its best to start with #7. That way everything is downhill from there.
I also heard that if you're anywhere near the 100K mark just go ahead and buy the new wires before you start. That way when one sticks (and you destroy it) you'll have the replacement right there with you.
Good luck, and come back and tell us howit went. We're always up for good entertainment.

Be prepared to give blood and brush up on your 4 letter word vocabulary.

The wires easily break when you pull them off so I would just get another set of wires and change them as well. Otherwise you'll need a lift to the parts store. A side ratchet might do the trick for an easier time with the plugs. I did it the hard way (with the trip to the parts store as well).

Purefun: thanks for the link.
Much blood was spilled in the battle of the dynamat many moons ago.
My hand are relativly slender, but i'll be sure to wear gloves...hands are important to a pianist.
I'm going to be swapping out the wires too. They wires on there look like stockers and there's 107K on the clock. I've decided on a set of the GM performance red wires since they the price is reasonable and people here say they are of high quality.
Thanks for the help guys, i'll be sure to return with horror stories
but first i have to wait until the parts get here.

What's the difference between the TR-55 and the TR 6?
also is there a difference between the red and black wires other than the color?
How do the MSD wires compare to the GM wires as far as longevity and conductivity?
Number 7 is the worst, so do it first and get it out of the way. Buy some anti-sieze paste and put a small amount on the threads of the new plugs. If you use decent wires such as the Taylor, you can discard the metal EMI shields. Also make sure that the engine is cold before you remove the old plugs.
