Spark Plugs/Wires - ZR-1 Net Registry Forums

1)With my top end off, I removed the spark plugs:
denso iridium IT20's and after only about 2k miles
I was surprised to see them all dark black "carbon-y".
Think I should go hotter to IT16's? Gapped @ .050

2)About 60K on the original LT5 spark plug wires.
Think I'll throw them away. Put your tongues back in-
only kidding. I have a set of Taylor 8.0mm wires.
Anybody use these before? How do they compare
to, say, Magnacore?
TIA
