Used Cessna Aircraft Canister Assembly Left-Hand Air Induction p/n 0850344-129. This canister does NOT include the filter element. This will need to be purchased separately before you can use this unit. (Filter element is pn 9910018-1, or BA108 and is NOT INCLUDED) Canister was removed from a Cessna 402B we parted out. We believe this canister will fit on Cessna Aircraft Model 310R with serial numbers R0701 and up, Cessna 335, all serial numbers and also the Cessna 402 with serial numbers B0801 and on.
