OEM 1971-74 AMC Javelin AMX Air Cleaner. This assembly has been refinished to represent the factory appearance as produced for the late 71-74 models. It features the later introduction of the thermal air inlet to late 1971 with the new pre-heater provisions. The base is in very good condition and has a single drain hole in the rear - allowing it to be used as either a closed element or Cowl Induction base, 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 interior features the correct air temperature sensor (ATS) retained by factory push nuts and comes with new vacuum lines to connect to both the snorkel and carburetor vacuum inlet. It is finished off with a reproduction AMC licensed 401 Four Barrel High Compression air cleaner decal and correct air cleaner service decal. A "Made in Canada" stamp has been added as a nice touch of authenticity.

The original dimpled wing nut well lid is in nice condtion as well and features a new seal. The assembly is completed with a period correct wing nut and new heavy duty air filter.

This assembly was available starting late 71, as Federal emissions and drive-by noise reverted the performance air cleaners to a this single snorkel with pre-heating requirements. It will work with the Cowl Induction fresh air systems designed for the AMX/Javelin Go-Pak optioned cars. 

This is a nice assembly that will enhance your restoration. Best of all, it is a genuine AMC product.
