Get the Green Filters. Doubt there's much difference between the two. They both say it won't void your warranty. They appear to be real good quality, make the O.E.M. paper ones look like junk. Install is a snap. I'm convinced my 350 has a slightly throatier sound. Don't know if my gas mileage has gone up, but it supposed to add a couple of miles to a gallon. Another bonus. |
