Does anyone have any experience with these...especially with a Mojave?? Do they make any performance improvement?? If you install all 6 does it require a jetting change??

I chose not to use these kinds of filters because people have told me that the foam can fall out pretty easy. I found my vents at thunderproducts.com and I love them. I can open or close them at will depending on my elevation.

 

Do the knobbies fit or did you get the flat ones?

 

I got the flat "fat boy" vents.
