1969 Chevrolet Impala SS Caprice Biscayne Sport Coupe 427/390HP L-36 Air Cleaner. This assembly was taken in as a trade and updated to present a more finished appearance. The single canted snorkel with oval end is in good condition with minor finish anomalies and features a fully functional ThermAC pre-heater along with new GM white-striped/black vacuum lines. The base is clean and comes with a correct 1969 air temperature sensor (ATS) installed with the correct GM retainer.  The exterior has a GM licensed reproduction Air Cleaner Service Decal (CT=69 427). Note that the snorkel is canted downward and is angled 45 degrees from carburetor towards the corner of the passenger side fender, as well as the breather filter on the passenger side - both specific to 69. An original pre-heater elbow is present and has the correct Wittek screw clamp as well. As an added value, a new pre-heater aluminum tube is included.


A very nice reproduction dimpled chrome lid enhances the assembly and features a new seal. To complete the package, a new heavy duty air filter, replete with a new breather filter and period correct wing nut, are included. To add further distinction, GM licensed 427 Cross Flags and Turbo-Jet 390HP (temporarily installed - permanent installation to be made by the buyer as required) decals are included. Note that 69 cars received either the chrome or black lid - dependent upon application. The 69 L-36 was featured in a very limited number of cars. Less than 2,500 full size cars received the top power plant for the year - many of the air cleaner assemblies were immediately discarded and never seen again. Rarity, coupled with correct parts, adds value to the remaining Impala SS/Biscayne L-36 cars. These assemblies are few and far between - restored or original - and are both highly coveted and desired. This piece will correctly replace the nearly always missing assembly that distinguishes the true car enthusiast from the rest of the 14" chrome air cleaner pack.

This assembly is in overall nice condition and will enhance your restoration. Best of all, it is a very rare and genuine GM part!

Many of our items are a "one time only" feature and may never be featured again due to difficulty in obtaining them.
