Highly recommend this air intake

Works great, sounds fantastic and I love the way it looks. Overall a good product for the price. It also states that everything is made in the USA.

Looks good - spare parts

Increased power by 5 hp. That can be overwhelming. I may have to put the original filter back in. 🀣 But seriously, it looks decent. I need to see how it handles Florida's environment.

Pros
  • Lots of positive emotions
Cons
  • Empty

FatBoy got colder after installing the air intake

Installed on FatBoy 2011 The extra air had a noticeable impact on my bike's operating temperature, which was my goal since my right thigh was idling or at 95 degrees on days at low speed even with the leather radiator installed.

Pros
  • Best
Cons
  • Functionality

Do not do that. Read and see photos

Do not install this on your Harley... I followed the instructions and you can still see that the red Loctite on the K&N supplied Alan bolt has come loose and fallen through the exhaust port is deals heavy damage. Garbage. The above reasons are all reasons not to do this. It will be interesting to see if K&N gets back to me. I am sending an invoice for onsite repairs totaling $3260. finish conversion. Don't repeat my mistake... Just don't buy it

Pros
  • Price
Cons
