K&N 63-1139 Performance Air Intake System, Black

Fit well on my 2018 HD 107. Looks good and increased performance.

I rings don't fit. Instructions tell you to use grease to hold them in place, but the don't provide any. Went and bought correct size rings and they stay in place without grease.Some bolts are really hard to get to causing the thin powder coat to get scratched when working spanners.

A little bit difficult to install. The cutouts around the flange are very shallow and hard to get a wrench on them. Made a difference in performance and starting the motorcycle.

I wanted more hp from my 2023. Adding this cold air induction would’ve done that.

Ok let’s get this right I love the product! BUT claims to fit a ‘17 road glide ultra it does not! keeping item but had to install flipped over!

Studs that hold the air filter to housing broke a week in to having on the bike didn't over tighten any of them was good for one week went on a 2 hr ride yesterday and 3 out of 4 broke

The neck of the air cleaner uses double end bolts that you screw half way into the housing the other half stick out and are secured with close end bolts. After riding I checked the bolts are recommended and tightened. one of the threaded bolts sheared off and is inside the housing where it cant be extracted. I did not over tighten or use any amount of force. Very disappointed especially since K&N has been around so long. Not sure what to do now since essentially it's a a $300 paperweight.
