NGK Iridium Plug Review

I installed the Iridium plugs on my Brute the other day and I will say one thing: They definitely improved the starting of the machine. I have turned it on and off multiple times over the course of the past few days and she fires right up a lot better than before. Heck, that alone was worth the 7 bucks I paid for each one.
Does anyone else use these Iridium plugs? Other than the starting improvement, they are not supposed to have much of a gain over the regular NGK plugs. I will keep track of my mileage and see if there is an increase.

After further research, I will be putting them in my cars as their main advantage is a supposed 120,000 mile life. I have read somewhere a 3% gain in fuel economy as well. Not that I would go 120,000 miles on my car without any tune up, but heck for a dollar or two more than stock plugs why not go with those.

Be very careful leaving plugs in for 120k.
I've seen a LOT of car/trucks with the 100k plugs get frozen in the head. They actually say that if you are going to leave plugs in for 100k that you take them out and rotate them at 50k.
One of the last classes I took when I worked for Ford was all about the plug rotation recommendations. I saw A lot of 4.6 and 5.4 engines with plus frozen to the point where we had to take half the engine apart to fix it.
