I am thinking about putting on aftermarket airfilter (UNI or Twinair) on my 2003 vinson. I am wondering if there are any gains to putting one on a stock machine. I want a pipe eventually and will for sure put on a filter then but for now will it bennifit me. Thanks and which brand would you buy.

 

I run a UNI on my Vinson.I've ran these filters on all of my bikes in the past and have had very good luck with em..You wont see any power difference until you re-jet and add a pipe though!

 

Is twinair a good filter. They seem to be pretty good or is UNI better.

 

I've personally never ran a Twin Air,but I've alot of good things about em.I would think that both being a foam filter,that they would be close in air flow capabilities?
