I have a 2002 GMC 2500, and was wondering if anyone has modified their air filter box. I was looking at mine the other day and was thinking about cutting out a section of the bottom and taking out the base plate that it bolts to. was just thinking this would allow more air into the box. it would be similar to a K & N cold air intake. The bottom is wide open. just wondering if anyone has done this or what people think of this idea.
