Depends what kid if filter it is. Some are reusable, some as k&n, they sell the recharge kit. If it is reusable just make sure to get filter oil on it after washing it. Use degreaser, a spray bottle, and a brush with the engine cold. You can search for other threads on cleaning the engine bay, theres a few in the DIY. I don't see why you would want to remove amything to clean. With a brush and elbow grease you can clean it up real nice. You can do the seafoam treatment if you wanna clean out the TB and such.
