OEM 1968 Chevrolet Impala Caprice Biscayne Sport Coupe 427/385HP L-36 4 Speed Air Cleaner. The assembly has been refinished in 60% gloss black finish to present a period correct image. The single snorkel with tapered oval end (as opposed to round for the Chevelle/Camaro assemblies) is in very nice condition. The exterior features a GM licensed reproduction Air Cleaner Service Decal (CQ=68 427). Note that the snorkel is canted downward and is angled 90 degrees from carburetor center towards the passenger side fender, as well as the breather filter on the driver's side - both specific to 68. An original style date stamp has been recreated to add a nice touch of authenticity.


A new reproduction 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 385HP (temporarily installed - permanent installation to be made by the buyer as required) decals are included. 

The 68 L-36 was featured in a limited number of cars. Less than 4,100 full size cars received the top powerplant for the year - many of the air cleaner assemblies were immediately discarded- never to be seen again. Rarity, coupled with correct parts, adds value to the remaining Impala SS/Biscayne L-36 cars tremendously. These assemblies come along few and far between. Finding one - restored or original - is both highly desired and coveted.   


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