D0WF-9600-A Air cleaner base for 1970 Q code 428 Cobra Jet engines with the ram-air option. *Trivia - all 1970 Cougars with 428CJ were identified by a Q in the 5th digit of the VIN. Only those Cougars specifically with the ram-air option used this air cleaner base. Note - it is not the same as the 1970 ram-air Mustang base. Additionally the 1970 air cleaner has a star marked plug next to the snorkel on the passenger side. Starting in 1970 this base also received a plastic elbow for mounting the breather hose to the oil fill cap. About 16-3/8" inches in diameter. Ford part number D0WY-9600-A.
