air silencer

You can take the silencer out from the inside of the airbox.Just remove the filter and reach in and collapse the edge of the rubber silencer and pull it out.You can trim all but about four inches off it and still draw fenderwell air instead of underhood air.
 
It still draws fenderwell air with the silencer removed. Where my airbox is, is about 2 inches from the fenderwell. The air people are concerned about drawing in to the filter (commonly referred to as "hot air") is the air coming off the radiator and fan, and the air down by and radiating from the exhaust manifolds. Forward movement of the vehicle draws most of that air back down the bottom of the engine compartment, and the intake still is sucking whatever air comes from the passenger side near the fenderwell (which is the air pouring in from the fenderwell itself.)

Either way, removing the silencer isn't worth enough to feel SOTP wise, but probably would be worth something if you had the power adders to require that much air volume to be sucked in at a time.
 
Is it worth anything?!?!?! Well, it will amplify the "sucking" sound that you hear through the intake track, which will make you think it's doing something, but in reality, I doubt you'll see more than a single horsepower if any from doing it. The SN95 airboxes are much less restrictive than the old Fox units were.
