I've got an early 99 F250 and am going to be installing a DIY intake. But just before I pickup the filter I wanted to know if anyone has tried an AEM oilless filter? They claim it flows as much as a K&N, but unlike a K&N it actually filters the air. I know you guys like the big filter because of the extra surface area, but installing a filter that big means that the engine will be sucking hot air. If I used the AEM which is only 7" in total diameter, I can box it so it would suck colder air from the outside. Any thoughts?
