After reading more comments on the forums regarding the stock paper filter, it would seem
prudent to purchase the UNI-filter (Part# NU-2486ST) for the KQ.

A couple of questions:

Frist, how is the Uni Filter held into the airbox? Do you need to cut the paper
off the OEM filter to use the factory plastic top and wing-nut screw to hold it in?

Second question, I went to their website and they give the price...but there is
no link to purchase. Are there any major auto stores selling them
or do you have to direct order from Uni-filter?

There is a picture of the Uni at their website Click Here

 

The Uni has its own plastic top. You need nothing from the stock filter, just wingnut and bolt. I bought mine off ebay, there is a ebay store selling them.
