Overview of K & N Factory-Style High Flow Air Filter - BU-9003

  • NON-RESTRICTIVE - dust and dirt will not clog the filter because they remain on the outside of the element
  • FREE-FLOWING - despite the outer layer of trapped dust and dirt, air flow between the particles remains virtually unaffected
  • MOISTURE-RESISTANT - moisture will not clog the oil-saturated element, even completely wet, the filter will allow the engine to breathe freely
  • MINIMAL-SERVICE - because dirt particles that build up on the outside of the element actually aid in the filtering action, frequent cleaning is not required
  • Unaffected by pollution control devices - oil breather blow-by is absorbed in the fabric without effect
  • Filter is pre-oiled

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

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.
