In have an AIRAID 401-272. It is what you would consider an open-top design, but they give you enough gasket material to make a pretty good seal with the hood on all four sides of the airbox. It is the dry, multi-layer filter, so no danger of gumming up the airflow sensor with filter oil. I have over 70k miles on the truck. No issues with the AIRAID intake at all. I'm quite satisfied.
A little hint: When you are working on your intake, take note of the shape and contours of the factory snorkel that sucks air from the inner fender into the airbox. It is a study in sharp angles and raw edges. A little clever work with a Dremel, hand file, and fine sandpaper will smooth the airflow into the airbox.
