Do K&N cold air kits actually do anything on a Silverado?
I had a cold air kit on my 2008 Silverado, but after getting my 2013 I decided on not getting one but instead just got K&N drop in replacement filter.
It looks like on the Silverado that the K&N cold air intake uses a similar intake location as the stock setup uses. Is it that the cone shaped filter is a better design?

After looking around, it looks like getting an Airaid MIT (Modular Intake Tube) is a good choice.
