OEM 1971-73 AMC Javelin AMX SST Cowl Induction Air Cleaner assembly. This assembly has been refinished to represent the factory appearance as produced for the 1971 models. 

The base features the vacuum pre-heater assembly introduced in late 1971. It is in very good condition and has a single drain hole in the rear - indicating it was appropriate to be used with the Cowl Induction  top, as well as the front breather tube. The flange is 5 1/8" inch and accomodates factory 4 barrel carburetors (Autolite 4300 models) as well as modern iterations of Edelbrock AFB and select Holley carburetors. The base is finished off with a reproduction AMC licensed 401 Four Barrel High Compression air cleaner decal and correct air cleaner service decal. The original fresh air lid is in good condtion as well and features the 4 dimple wing nut well. The assembly is completed with a shelf stock air filter and period correct wing nut.

The Cowl Induction flapper assembly is in excellent condition. It is complete with a new vacuum actuator that allows the trap door to provide fresh air to the engine and has been installed with Rivnuts using lock-tite for ease of service. The door functions smoothly with the supplied vacuum line, while the OEM seal remains in very nice condition considering it is over 45 years old! Since the seals are not reproduced by anyone, this is indeed an exceptionally nice piece! "Made In Canada" stamps have been added as a nice touch of authenticity.

This base assembly was available from 71-73 production runs. It will work with the Cowl Induction fresh air systems designed for the AMX/Javelin/SST Go-Pak optioned cars. Note that the very early 71 models featured a straight tapered snorkel without the vacuum actuator; this changed around mid-year of production due to Federal emissions requirements. The final picture illustrates how the entire assembly was completed via a factory diagram.

This is a unique assembly that is both very rare and highly coveted by AMC enthusiasts.



This assembly is correct for the following 1971-73 401 models:


Javelin AMX, SC Hornet, SST

It will fit a variety of AMC cars from 1968-1974 featuring the 343/360 engines as well, but is correct for the 71-73 401 models with the Go Pak and functional Cowl Induction Hoods. The 74 models were further restricted and were not offered with these systems du to the EPA and drive-by noise restrictions. 


The assembly will fit factory 4 barrel Autolite carburetors with a 5 1/8" diameter flange, as well as Holley (non-double pumpers), Carter, and Edelbrock variations without electric choke (some adjustment to the carburetor alignment tang may be required).
