🏍️ High-Performance Air Intake System: Harley Davidson 2017-2019 107 M8 Touring Models Street Glide Road King Fat Boy Freewheeler RK-3956 by K&N Review

Looks great on the bike, one small complaint is my foot touches that air intake. This sucker also has a habit of warming up a bit. Time will tell if I leave it enabled or try a different version. But it looks great and sounds great too.

Ease of installation and throttle response from my other aftermarket air cleaner is different day and night. It's worth upgrading the Milwaukee 8 engine. *Re-tuning highly recommended and really worth it*

Very good airflow The design removes the breather tubes which impede at least 10% of the airflow by directing it through the base plate, it's quite a gimmick, also there is a rubber quick dial that doubles as a spacer and retainer for the carburetor Fixing screws is used

Seems to be a well made filter unit and back plate but once installed it doesn't sit flat in relation to the rest of my bike. Doesn't affect performance, but is a little annoying. I think kn uses the same part number for touring M8s and they may have the motor in the frame at a slightly different angle to the ground. Just a guess.

Fairly easy installation. Use the included bracket like any other part of the Large Twin. Good looking, breathable from all sides, reusable filter. I have used K&N for decades and they have never let me down. I've driven 500km and haven't had any problems so far. It sticks out a little further than a standard air filter, but not far enough to be a concern. to me.

It was very easy to install and worked very well. As others have said, this puts my foot in a slightly awkward position, although it's not a BIG thing. Unfortunately had to go back. The included bleeder screws eliminate the hose that redirects oil backflow from the inlet port, causing the water/oil mixture to hit all of the screws. This is not a fault in the intake manifold, but a design flaw. I had to create an external ventilation system at the bearing inlet to prevent the old oil from…

I spent $280 not to start with this! around the air filter) and now I have this. Of the 3, this filter provided the most obvious and immediate improvement. great (planning to add a footboard extension when I put the new exhaust in anyway). My exhaust IMMEDIATELY went deeper and louder on the first run after installation, throttle response is AMAZING now. From a fuel economy standpoint, the tune I used for the Screaming Eagle filter is still good (the Harley SE tuner claims I have a map ready…

It's very easy to install. Directions in colour. They're a little vague, but anyone with common sense can figure it out. I have a 2019 Road Glide Special with a 114ci engine. The installation of the air filter kit was spot on and a perfect fit. The only thing to remember is to install 2 long washers on the new backplate before putting the new backplate on the bike. They have internal threads on both sides. One side to connect to the back panel and the other side to hold the filter. On my…
