Has anyone used a Green Filter on there Ram? My dad came home from the gas station and said another Ram parked next to him, he started talking to the guy who worked at a Protrucks and the guy was insistent they were better the K&N.
I looked at their site and there isnt much information. They're a couple dollars more then K&N and I couldn't find anything about a warranty on them. So far the K&N seems like a no brainer to me.
