September 1, 2015 - Part BU-9003
Instantly noticed improvement when combined with open air box kit.

Noticeable difference in throttle response with bone stock configuration. When I switched exhaust to aftermarket, I felt like noise increased and power decreased. But I think my ecm needs remapping, nothing to do with the great k&n filter.
