engine air filter to change

I own a 2001 Newmar dutch star with 330 hp cat. with a freightliner frame. I have been looking for the engine air filter to change. Does anyone know where it is for sure and how to change?

On my freightliner the air filter is near the muffler at the drivers side rear. The air filter on mine does not have a replaceable cartridge like most automobiles.. It is a large metal cylinder maybe 12 inches in diameter and maybe 14 inches long.

Motorhome chassis builders are in love with the Farr Eco lite filters. They can flow in either direction and are pretty compact for their flow rating. They are mediocre at best. They also force you to open the intake system every time you chance the filter making at air leak on the clean side more likely.

Here are some examples:


These are all manufactured by Farr and sold by many other filter manufacturers.

rhuff, if your '01 has a side radiator, it may be identical to my '02. My intake air filter is located above the engine, and (looking forward from the rear hatch) behind the coolant expansion tank. A round, cylindrical thing a bit smaller than a 5 gal bucket. Access in my MH is through the removable floor of the bedroom closet. (two lag screws under the carpet through the floor into a frame member) Removal/install is a bit cumbersome but not particularly difficult. There are 4 air hose clamps to remove, and two big band clamps around the filter case to release. Have a big tough plastic trash bag ready for the whole assembly. Take it outside to remove/change the old element, or there'll be dust all over your bedroom. Someone will be aggravated.
