This listing is for one engine fresh air intake removed from a 1977 ford F250.   It will fit the 1977-1979 Ford Truck & 78-79 Broncos and possibility all the way back to 1973.  This is one of the pieces that connects the core support to the Air Cleaner on the engine on the passenger side of the engine compartment.   The piece is very solid and the mounting tabs are all present.  It is a little dirty bit it will clean up nice.  This was removed from a 1977 F250 with the 460 engine.
