Some folks feel while there have the plugs out anyhow, might as well change them. How many miles on your plugs?. Same thing for the plug wires. If the factory wires are good no need to change. Be careful when you remove them you don't damage them. I do recommend that you put Kool Socks on your plug wires to keep them from burning. :cheers:

I currently have 12,000 miles on the car, how do you know if a plug is bad?

Pull all the plugs. Compare. If any look different, blacker and/or oilier than the rest, it's got a problem.

I changed my plugs at 20K miles, when I installed the Vortech, per Vortech's recommendation. Without a doubt, the plugs that came out of the car were perfect. They looked like they'd been in the car less than 1K miles. There was no reason at all to replace them (but I did anyway since they were already out).

Isn't it usually a good idea to change to a colder plug when doing a blower/nitrous mod? That may be why Vortech recommended it on your car.

Yes, general rule of thumb is one heat range colder :z:
