I had an AEM air filter on my jeep cheorkee, and my dodge neon.. Loved the fact that you did not have to oil them. Just wash them. And they are suppose to filter better than a K&N..

Seeing how a K&N is setting of the CEL's soo much.. You would think the AEM drop in would be the better way to go..

Maybe if we could all get a ton of us HHR owners on here and some one knew how to bug them enough... Maybe they would make a drop in for for our HHR's.

Any one had any experience using a AEM air filter before? I know they make a universal cone filter at the stores.. But I don't see changing in my opinion a very good stock air box setup.
