thanks for the replies guys, I am wondering if the dry system is why his check engine light came on or not. I guess it is different than the Pro Guard 7 version but i don't know that either. I really want to put on a dry filter really bad but i definitely don't want check engine lights on. Maybe i will give them a few more months to get the bugs worked out of the system. I had an AEM dry on my 6.0 and never had a bit of trouble with it, they just don't make it for the 6.4 yet i don't think.
