K&N Cold Air Intake System: High-Flow Air Filter, Increase Performance & Acceleration: Compatible with 2001-2017 Harley Davidson: (See Product Descriptions for Select Models), 57-1137

Decent performance for the price. I installed this on my 2014 Wide Glide and put one on my 2022 Fat Bob (different part #). One thing that made installation a little easier for me was starting 2 of the acorn nuts on the intake tube without washers and snugging them down which makes it easier to thread the other 2 on with washers. Then remove the first 2, add the washers and tighten all 4. I didn't need the spacers.

Fits my 03 road king classic just fine. Defiantly could feel a difference in HP and Torq. A little to big for the look im going for but performance wise its great.

Easy to install

Awesome cheap upgrade with needing to retune the bike. K&N appearance is top quality

Everyone told me... you won't like it, it will get in the way of the brake, your leg will hit it. None of that was the case, I'm damn happy I bought it. It's not a safty issue whatsoever for me. I do have control extensions on, & I'm 6ft. I love it, I don't like the cheaper ones, but the K&N is cool af in my opinion

The media could not be loaded. Overall seems to be a pretty good product. I’m gonna take it out on the road tomorrow so we will seeDidn’t really add a whole heck of a lot of power just a little bit of throttle response pretty easy to put on.

The KN air filter kit for my 06 Harley Softail is one of those items that either appeals to you or it doesn't. Personally, I appreciate its look and the benefits it provides. However, I understand that some people find its size and location to be a bit awkward. Ultimately, it comes down to personal preference and whether or not it aligns with your aesthetic and functional preferences. Only complaint was getting the small mount screws was pain.

I went out on a limb to see how this would fit on my 07 Electra, and im not disappointed. You cannot use the filter that comes with the kit unless you have no lower fairings, but that's ok, a quick trip to O'Reilly for a $35 specter stubby air filter with a 4" inlet slips right over the entire housing and gets the job done. Makes a pretty good sound and feeds my 10.8:1cr 107ci Twinkie well. Also is the perfect diameter for a 62mm throttle body opening! Just trim the gasket a little once it's installed for a smooth transition of air. Over all. I'm happy with it.Ps ignore my ratty pipes lol.
