OEM 1968 Pontiac Firebird Lemans Tempest OHC-6 4 Barrel air cleaner. This assembly has been refinished to the original look of the 1968 cars featuring the hard to find Sprint OHC-6 engine with the 4 barrel. This set-up is unique to the 68 Pontiac OHC engines due to the snorkel angle and 5 1/8" carburetor flange (Chevrolet featured a parallel snorkel for their 230/250 engines this year). 

The base features the oval canted snorkel with ThermAC pre-heater door and large inlet on the bottom.

The inside is clean and has a reproduced date code to add a nice touch of authenticity. The bottom of the snorkel features the larger ThermAC preheater inlet.

An original survivor chrome air cleaner lid ( 8 of 10) with an original silencer pad is very clean and presents well too. 

The assembly is com

pleted with a new heavy duty air filter, new valve cover breather filter with clip, and period correct  wing nut. The assembly is in nice condition and will add to your restoration. Best of all, it is a very rare and genuine GM parts.

Many of our items are hard to find and there is no guarantee we'll get another back in stock. While we strive to maintain diversification, demand often exceeds supply. As such, the old adage "here today, gone tomorrow" applies.
