Not until a bunch of dyno runs was I fully aware, but you do have to mod the intake in order to see the hp gains with the K&N. I've tested the drop-in against stock in my dyno thread, and hp wasn't seen until the snorkel-delete/ram-ish mod were also installed. But you will notice increased throttle response.

My next dyno will include the current mods along with the Newmission mod. I anticipate seeing a little bit more than where I am currently, which would put me equal with the actual CAI's available.
I did the snorkel ramish mod when I did my filter. I also removed the silencer but that didn't really do anything at all.
