Had the same problem with ny #5 R.F's and Msd wires. I would rather know they were good and tightly sealed than loose. Can't win em all, especially when we deviate from stock. I don't think these parts are bad, but personally next time I'll be putting my ignition parts back to stock. Maybe my tach will start acting normal again.

Lone Ranger, I have the Rapidfire #5/Taylor 8mm Spiro Pro combination and have absolutely no problems regarding too tight a fit....maybe its because I have the "earlier design" Rapidfires since I have a '90?

AC Rapidfire Spark Plugs
I've never used these but the problem seems to be directly related to vacuum within the boot. I mean, the plug boot is creating a vacuum inside and the harder you try to pull the boot off, the stronger the vacuum becomes. May I suggest inserting a volt meter(the one with a small needle point) or similar tool into the top of the boot, pulling it to the side thus creating a very small hole which should release the vacuum inside the boot. Hope this works.

WOAH! Not calling anybody incompetent here.. I even said it happened to me a few different times in the past with different plug and wire combos... Just sounded to me like you jumped on AC delco for a poor design to something that can happen to just about any plug... didn't mean to get you ruffled up I'm sorry.
