So I recently replaced my stock air filter with a K&N air filter. In the process I noticed 1 of the rubber grommets was missing. As I read in another thread, those rubber grommets could obstruct the radiator fans right beneath the air filter. From what I understand, removing the tray should give me a good luck at the radiator fans?

Are there just 4 bolts to take off or is there more required? I'd like to do it myself but also am not much of a car mechanic.
