I haven't installed anything yet. They told me on IG that the sound is almost the same, but they are going to say that anyway. The paper filter they provide is from Spectre. There are a couple of people on here that have said they have switched to K&N.

This link is to the conical filter list by sizes: https://www.knfilters.com/search/univcone.aspx

The Spectre filter they send is about 3.8" in length. I haven't gotten a for sure answer on how long of a filter can be fit, but I am assuming maybe a 5 or 6". The tubing calls for a 3.5" flange.
