exactly what it should be
While this may not be the best if you are looking for a great increase in air getting the motor such as a full kit would be. This is exaclty what they state it is, a high flo OEM replacement style filter. It surely is better than stock. If your looking to replace the stock filter with a better quallity high flow filter without out going crazy with an entire new setup then this seems to be a great option. I like it and it was super easy to install.

Good Deal
If your going to pay 60 bucks for a stock filter from the dealer your better off paying 60 for a K&N and letting it breath better

Can't go wrong with a K&N. Hold up better that other reusable paper style filters.

Great product.
I purchased this K&N air filter after a cross country ride and I wish I would have done it before. Noticed a big difference in the way my 06 Ulra Glide runs. I would highly recommend this air filter over the stock one.

simple and effective
I have a 2010 iron 883 and threw on scream-in eagle slip-on to get rid of the stock chrome pipes. The look was great but the tone lacked something, an air filter that flowed just above a stock paper filter, the k&n was perfect, it fit in the stock unmodified filter housing, had it in in two min. It gave the bike power at the top of every gear and aided in throttle response through out all ranges. the only downside was it twas twice as heavy as the stock filter. it was perfect for a slip on setup without any power commander garbage.

K&N - Great as always
Filter seems to be working just fine - it's a filter....it is a bit of a tight fit compared to the stock filter, but it does fit and it's the best filter that I know of!
