Stock seems to perform better
Not happy with the performance of this filter. Installed around 30 days ago on 2008 Wrangler, 6 speed. Loved the sound it produced and the throttle seemed a little more responsive. A few weeks ago I started experiencing some issues with start up and the engine seemed to run a little rough. Checked the hose, the temp sensor seating, and made sure the o-ring were all tight - no leaks and everything seemed good to go.
I switched back to stock just for kicks and the Jeep idles better and the engine seems to run smoother overall. I'll miss the sound the KandN produces, but I'm keeping the filter off. I see no benefit in this filter.
