OEM 1963 Buick Riviera Air Cleaner Assembly in very nice condition. This assembly has been refinished to a period look of the 1963 cars featuring the exclusive red wrinkle finish. The base retains a very clean interior and the indexed 4 1/8" carburetor flange designed for the original Carter AFB carburetor. The snorkel is straight and is garnished with a GM licensed Wildcat aluminum emblem. 

The OEM lid is clean and also presents well and is finished off with a new "Riviera Wildcat 445" aluminum silk-screened engine identification plate - again, specific to the 63 cats. Note there is a very small mark on the plate at the 7:30 position - minute and hard to see once installed, but mentioned for clarity. The assembly is completed by adding a heavy duty air filter and period correct wing nut. 

This assembly is in nice condition and will add to your restoration. Best of all, it is a rarer and genuine GM part!

Many of our parts are available only once due to limited availability. There is no guarantee that we will acquire another due to scarcity and limited access. As such, the old adage "Here today, gone tomorrow" applies.


This assembly is correct for the following:

Riviera 401 with 445 lbft torque rating

Note: this will also fit the 64-65 models - these were painted black (64) or completely different (65), but this assembly certainly adds a flare to your engine compartment.
