Really helps

I put this on my 2012 Street Glide. Also use the K&N Fuel Pack FP3 to tune your bike. You can hear it sucking in air as you roll over it. Definitely increased my performance. Only gave 4 stars because the chrome plate is not perfect. It's not visible in the photo, but from one angle you can see it's not quite flat. It seems to have some waves in it. Not Raven's fault. I will contact K&N and see if they send a replacement.

Pros
  • K&N heavy duty washable large air filter extends life
Cons
  • Ugly packaging
