Getting them out of the deep well can be a pain at best; I take a piece of vacuum tubing (I used one from the PAIR valve that was removed when I installed SNARF's most excellent block off plates) which will easily slip over the spark plug tip. Easy peasy to get it out once completely loosened and easier still to start threading the plug when you are installing!
Oh now your just making me blush
Someday, I hope to be able to use the tubing from the removed PAIR valves for this...
Just kidding, snarf.
I'm sure my block-off plates will show up eventually.
NOTE: For anyone reading this, it's the fault of the USPS (and, apparently, a suicidal deer) that my plates haven't arrived.
