Changing spark plugs/wires
I was reading in the C5 tech section about changing the spark plugs and ignition wires.

I was wondering if the NGK plugs and Taylor Spiro-Pro wires mentioned in this article provide any noticeable performance increase over stock? Currently, I have about 42K miles on the original plugs. My car is basically stock (only mods being a Blackwing intake and probably adding a cat-back exhaust in spring.) Would it be worth it to change the plugs/wires?

The stock wires are quite good and new wires won't have a performance gain on stock wires in good shape. Having said that you still may want to get a new set of wires. If the wires haven't been off in 5 years you make break some getting them off.
A good replacement plug is the NGK TR55IX. They have very long life and excellent combustion characteristics due to their very small profile in the combustion chamber.

just another FYI I did the wire swap recently and just for my own info I checked each plug and wire as I removed them....using an ohm meter I checked each wire and found all but 1 to be in good shape..never could tell while the car was running...but I would say it probably time for a new set

I put a new set of Taylors on because I pulled the stock wire apart trying to get it off the infamous left rear plug. I didn't see any performance improvement, but they sure look better.

I did the exact thing a few days ago. I broke one wire taking them off and found another one corroded. I replaced them with the Taylor 409 wires and replaced the plugs with the NGK TR55IX. I think it runs so much better, and even has more pickup and go. I guess that's because my wires were all messed up. I say go for it.
