I've decided to change the air cleaner presently on my '06 Ultra Stage 1 and I was looking at the different types/brands on the market but I'm afraid to make the wrong choice,is a retuning needed after the change?Suggestions are welcome,thanks.

 

My dealer (who doesn't mind tuning a bike outside of the factory tune) suggested that I get it tuned after an air cleaner change, especially if you already have aftermarket pipes.

I had the same questions about which air cleaner. The answer I seemed to find was that it really didn't matter as long as a had a high flow K&N type filter.
