Great plugs!
This is my second time buying from the Iridium-IX product line for my vehicles. Bought these plugs with the wider .044 gap (code BKR5EIX-11) for my 2006 Scion xB. The larger gap is said to allow for a better spark and improved gas mileage. (As I understand it, timing is retarded slightly to account for lag created by the larger gap.)
Anyway, here is what I have seen so far:
-Idle is now super smooth. Before, the idle would hover near 900rpm and then suddenly drop, then back up again. These allowed for a solid idle that stays around 1k rpm with no dips. The (stock) plugs I replaced had less than 12,000 miles on them, and did not show signs of abnormal wear or other issues…so I don’t think they were specifically bad, just not as good as the new iridium plugs.
-Acceleration “feels” stronger and smoother. (no dyno testing or anything….just how it feels to me)
-Mileage has increased. I am getting about 2-2.5 MPG more with these plugs….that’s about an 8% increase…..not too bad in my opinion.
Also, being iridium, these “should” allow for a longer service interval before they need to be swapped out again. (Though I will likely not let them go anywhere near the 100k that they can reportedly go….especially since I went with the larger gap to begin with.)
Update (9/5/2010): This item is currently on sale here for the lowest price I’ve seen. I also found some auctions for this item here.

Honda Idle
My Honda Foreman 500 used to be very cold natured until I put this plug in. It now doesn’t need to be started by choking much of the time and when I do have to choke the engine, it can be unchoked after starting where I used to run with choke for a while before it would stay running. Great plug.

Great Plugs, Well Worth It
Have used cheaper plugs in my 2002 Ford Escort (Autolite, etc.), you can notice a difference in engine performance (although that’s a highly subjective statement).
Only other plugs I currently recommend are the bosch.
