Does anyone know if there is an inside air filter for the Duramax? I saw one made by Purolator at the pureoil.com website and am curious. Thanks to anyone who answers.

On the 99-02 trucks there is a cabin filter. 03 and newer there isn't a filter anymore.

I thought I read on here somewhere as to how to cut one in. I understood it to say everthing is the same in the duct-work you just need to cut a slot where the filter belongs. Edited by: Jumper357
