Spark plugs

What is the best sparkplug for the 97 Aurora? I have a skip after 80,000 miles on original AC's.
Should I stay with AC's?
thanks

Yes you should. Go ahead and change your wires to (AC their too).

Absolutely AC DELCO Plugs and Wires. The coil pack comes off with 4 10mm bolts. 2 on each end, two in the back. Get those puppies off and go to town. Best to put a small drop of "Never Seize" on the threads of the new plugs as well. On the back plugs I found that 2 3" extensions worked better than a solid 5" extension - which is a little bit long. With the two extensions, you can disconnect the one and then pull the other and the plug out easily. Be sure you have a good Spark plug socket too!
