Great
Superb bit of kit. Looks great and sounds great on my Harley FatBob

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.

It not in the way for your leg.
What a look if your engine is blacked out. Changes the sound a bit.

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 satisfied!!!
I did not ask for a replacement. I am not taking the part off my bike to return it. I simply wanted the missing piece. I do not expect to be charged for the new replacement.

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.
