changing spark plugs
Damn, I just changed the plugs on my new to me 98, just over 90 thou, and original plugs and wires. Talk about a pain in the ... I had 5 bandaids in the house and I ran out. I had to put a short cheater bar on the ratchet to get them loose. New plugs went in fine, but nothing like taking 2 and a half hours to change plugs. I hope that putting headers on will ease my pain in the future. Oh and I did put anti-seize on the new plugs so that might help next time. Randy

They can be a chore to change. Good idea about the anti-seize.

Thanks for the warning! 
What plugs are you guys using? I've got an 04 Z06 and like to change them in a few weeks so if you guys wouldn't mind sharing I'd appreciate it.

I quit after breaking two spark plug wires on the driver side. I'll complete the job Thursday, waiting on new wires.

Well, the first couple of times I did mine it took a couple of hours, but I can do them in about an hour now, that is what happens, when you end up doing headers, heads and just plug swaps at different times.

I went with the double platinum from napa APP104, but only because I had not read any plug threads. The ones I took out of the car were all around .73, due to all the pucks being off. I asked the dealer what they charged and they wanted 300.00. It might have been worth the extra money.

ehh... platinums last longer but they also burn hotter. Plus gapping them with the flat blade tool ruins them. Need a rounded gap tool.
I tried the Bosch +4 in mine because my friend got me a free set and noticed not one da** bit of difference. My language just got worse getting to that last M-F'er of plug near the windshield on the driver side.
I'm not racing at Daytona, Indy, or the Gator Nationals so I'll just stick with the OE plugs next time.

Last season I replaced my plugs for the first time with NGK Iridium IX plugs (TR55IX) and noticed a difference in performance. However, at a price of about six dollars a piece I will give the NGK TR55's a try next time .
There is a thread on how to change your plugs on this forum. I used the advice, purchased what was recomemed, and it took me only one-half hour per side without shedding any blood or brused knckles

It's realy not that hard. Save the money and do it yourself .

If the previous plugs aren't stuck in there real good, it is not a hard job to do. When I got my car it had only 31k on it and I changed the plugs within a few weeks. All of them came out easily and the entire job only took me 45min.
I now change my plugs every 6 months (about 8-10k) and find it's a super easy job. I never tighten them in there too much, so the next time around it is quite easy to get them out.
