In the 2 days I was running with it before an elk decided it wanted to ruin my week, I was already noticing performance increases and higher mpg's.

The savings of having this filter alone makes it worth it. Not certain on any performance gains. Wish K&N would work on some of the other HD intake filters that aren't cylindrical.

Arrived in a timely manner, easy install. A little hard to find on your site.
