Original spark plugs changed out on a 2004 XLR with 88K miles - pictures

I changed the spark plugs on my 2004 that has 88K miles on it. The plugs were the ones it came with from the factory, did not look too bad. here is a pic arranged the way they were in the engine. I replaced them with stock AC Delco. I can tell the difference with the new plugs, runs smoother.

Hi BB, did it require using a tool to remove the coil paks so not to damage them? I thought I saw that some where but cant locate the thread.
