Upgrading from the stock breather to this one was a breeze. However, if you're riding a 21 FXLRS with the low-profile breather, be prepared for a significant size difference—this one will feel massive in comparison. I wouldn't recommend it if you're using forward controls, as it's likely to get in the way. But if you're sticking with stock mid controls, you should be good to go. As for performance, I haven't noticed any improvements yet, but my tuner is still getting acquainted with it, so time will tell. Aesthetically, it's a real winner—the red filter complements my maroon bike beautifully, making for a pleasing overall look. Read more

Overall I"m really impressed with this air cleaner, particularly for the price. It's solid, and looks and feels like high quality materials. The backing plate is all metal, so an immediate improvement from the junk plastic that comes from the factory on these M8 motors. Everything lined up and fit perfectly on my 2020 Road Glide, and it really looks nice on my bike. The filter element is similar to other (much more expensive) air filters that I've ran in the past. The only possible complaint (and not really a complaint), is that the clear window is pretty thin plastic... so I'm not sure how long it'll hold up. If it distorts or gets scratched, I'll just replace it later with some thicker plexiglass. it comes with all the hardware needed to install it on your M8 bike, and installation was simple and straightforward. My bike looks better, it sounds better, and maybe even runs a little better... all for under a hundred bucks! That's definitely a winner in my books. I'd buy it again for sure. Highly recommended.
