  • NEVER UNHAPPYwith K&N so far.
What a great product! Comes with the dyna test comparison, simple installation, fluid purchase with fast shipment... who can go wrong? THE HOSE LINED UP FOR ME. Bike is still in rebuild process but almost road testable. Updates to follow!!!

  • 883 Iron
Bought this for my 2014 883 Iron. It went on without any problems and everything fits perfectly. It looks very sporty and adds 8 HP. I also bought a rain sock for it. I highly recommend this product and would buy it again if needed.

  • I have K&N on most every vehicle I have owned the last 10 years.
Amazon had the best price I could find. Even after days of looking on other sites. First one for my Harley. What is not to like about K&N!!

  • Good product
Good product, would have been 5 stars but they sent the wrong size breather bolts. They shipped the right ones pretty fast though

  • Kinda cheap.
The vent doesn't line up. I tried loosening everything and even taking it all off twice and it just doesn't line up. I thought it would still breathe enough but I ended up blowing a gasket because it doesn't actually vent. I can modify it but I shouldn't have to for the price.
