Perfect fitment better throttle response
Looks fantastic! Ordered this to replace a screamin eagle intake. At 5'8" the stock "football" cover really got in the way of my knee with forward controls, the k&n is still a little in the way but not nearly as bad. I immediately noticed a snappier throttle response and the ol butt dyno says it's got a little more power. Fitment on my 09 fxdb was flawless and installation was a breeze. The included instructions even have color photos, took 20-30 minutes to install with absolutely zero issues.

Good quality
Fit on my 2011 Harley Softail Blackline, bolted right up with no problems and was an easy upgrade from stock.

2008 FXDF Fat Bob
Easy install and looks great on 2008 Fat Bob. Changes sound a bit. Not noticing a difference in performance but bike does backfire less than before. Drag Pipes were already installed and I have yet to tune. At this point, running well and don’t see a need for tune. Overall good purchase, nice look and maybe a bit more power.

Not a happy customer
Came from the factory with a bad threaded head bolt...also two screws that held the outer cover on was cross threaded. I had to find a hardware store that sold something similar so I could install it. I have K& N filters on both bikes and filters in three vehicles. This was my first ever issue

Great in every way
Delivery with Express, great job. Look is very suitable for my taste. Must do a Mapping for the Bike now. The only thing is, you need a bypass plug because my 2014 Twin Cam has a Connection. But no problem with the Bypass, 20 Euro.
