From what I understand, the factory intake is a pretty good setup. Do you think I would benefit from just a drop-in K&N filter?

 

My experience from running K+N drop ins on many vehicles is that you aren't really running them for a huge performance gain, or even a noticeable gain. I run the for the serviceability. Just be sure to keep your stock filter to drop in for a day or two when you are cleaning/oiling the K+N.
