I change mine every Spring, no matter the mileage.
I also run one step cooler than stock
I prefer NGKs (from my shop owner days) but Autolite, Bosch, Champs will do
Fresh plugs are the cheapest performance mod you can make.

My 08 Ultra the book calls for inspection every 5,000 miles and replacement at 20,000.

I might give the Iridiums a try this next time around. There are a few of my friends that swear by them. They supposedly keep the engine starting/running smoother and acutally add to the power/torque slightly. You're only buying two of them so it can't be too expensive.

change them before they start misfiring, trust me. thought I could get a couple thousand more out of the set i had. Was gonna change them before our vacation, but things got crazy & I spaced it. went from a slight misfire to pulled over in less than 20 miles. We were stranded for about a half an hour. Sure felt like a dumba$$

Go for it, spend the $6 bucks, bike will run smoother.

After trying numerous style plugs I went back to the stock HD plugs my bike runs and idles better. I save my lunch money and change my plugs every other oil change.
