      These washable and rechargeable filters use a special coating to help filter fine particles from the incoming air. With time, the oil in the filter will dissipate and the element will begin to turn gray. Clean the surface and renew the original red color with an application of K&N Air Filter Care products.


      High-Flo K&N Air Filter Element is rated 5.0 out of 5 by 2.
      Rated 5 out of 5 by from This filter really makes a difference! This K&N replaced a standard dry element of the same size. Immediately noticed a difference in higher rpm response. Previously on occasion, motor would spit and hesitate. No more of that with this filter! Great product, would definitely recommend!

      Rated 5 out of 5 by from K&N Doesn't Disappoint I've been using K&N reusable air filters in my vehicles for almost 20 years now, from cars, trucks, to my dirt bike. It's one of the first things I replace whenever a new vehicle comes into my possession. So naturally, when I purchased my 2016 FLSS, I wanted to do the same. My bike came with the Screamin' Eagle stage I kit stock on the 110 engine, so this K&N was a direct, easy replacement, for the original filter; no adapters or upgrades to use this. It's got a nice finish on it's face, so if you don't want to use the air cleaner cover you can leave the filter uncovered, and it will still look good (I prefer the look of the cover, but that's just me). It was pretty easy and strait forward to install, just remove your cover, and unbolt the three bolts holding the stock filter in place, and to install the K&N, just reverse the process. After install, I took it for a spin. I noticed an immediate improvement over the Screamin' Eagle filter. Throttle response was better, and you can actually hear the throttle body gulping in air through the filter. Cleaning these filters is a snap, and I've had plenty of experience cleaning them. It's a good investment to buy one of these.

      Q & A

      Can I use P/N 29400020 or P/N 29400019 or both?

      Hi! I have a Screamin' Eagle High-Flow Air Cleaner Kit P/N 29400234 installed on my Softail Deluxe 2016 FLSTN. I wanna change to a K&N air filter instead of the filter which is in the installed kit. Can I use this K&N Air Filter P/N 29400020? Or is the K&N Air Filter P/N 29400019 the only right one? Or both? I like the look of 29400020 better cause I wanna ride without the air cleaner cover so my hopes are that 29400020 will fit my bike. /Regards from a Swedish biker

      Can I use K&N Air Filter Cleaner, part # 99-0606 to periodically clean this filter?

      Similar part number is attached. I would use per the directions, except do not apply the oil applicator that comes with the K&N kit that I bought.
      Asked by: abc58

      This filter element works in the Screamin 'Eagle Stage I Air Cleaner Kit Part Number 29400239 or should I use the K & N HD-0800?

      Asked by: Roka
      This will work perfectly for Stage 1. The HD-0800 is an OEM!

      Is the Screamin' Eagle High-Flo K&N Air Filter Element-29400020 the same as the K&N HD-0800 Air Filter?

      Asked by: YJRay
      Nope, the KN HD-800 is a replacement for HD-29400015.

      Will it fit the 2016 XL883N?

      Is is a plug n play or would it require any more mounting accessories? Have not seen a pic of the stock air filter on the Harley Sportster XL883N and am wondering if this is somewhat identical in material and workmanship to the stock filter? The K&N site too does not feature the air filters for the Dark Custom 2106 XL883N models...
      Asked by: GetRohit
      Looks like I ordered the wrong part through K&N, their model KN HD-800. Got my 2016 Dark Custom Iron for its maiden service at an authorised Harley Davidson Service Center and happened to look a the OEM Filter and took some snaps. The part reference on the K&N site is misleading!
