What is everyone using for air filters? Do you use conventional paper or a performance filter and why? I have 2008 Cobalt for commuting (app. 2500 miles per month), not looking for performance. Not sure what to use.

 

We have a 08 cobalt lt and I switched the factory filter with a K&N about 2k miles ago. It has just under 10k and it has picked up a little bit of power, and 2 more miles to the gallon.
