There is no such thing as a 100,000 mile OE spark plug wire. Most of the cheap aftermarkets will give you around 10,000 serviceable miles before they need to be replaced. The OEs maybe around 50,000 IMHO.

plug wires work great. I don't have an misfires or anything. The hard misfire on cylinder 4 was caused by a broken plug. Not sure how it all of the sudden broke after a year of use. I no longer have the minor misfire either though. Wires were perfect length . The only thing I was worried about is that it doesn't seem like the wires really click onto my iridium plugs.

Not a guaranteed 100k miles, but my OEM wires have been exceptional performers. First wire change at 120k, 2nd change at 246k, now on 3rd set with no issues. I see no reason to try any other type.
