Alamovet,
I ran a K&N in my previous truck until it developed pinholes and put a GM filter back in. With the K&N I had several wear metals that kept showing up high along with high solids. After I put in the GM filter, almost every reading made huge drops. To top it off there was no difference in fuel economy or feel in the power. If you are going to use one expect the extra wear.
