1970-71 Mopar 340 Four Barrel Dual Inlet Unsilenced Air Cleaner. This assembly has been refinished in wrinkle black to present a period correct image. The base is in excellent condition and features a 5 1/8" carburetor flange that fits the Carter Thermoquad carburetors along with the correct unsilenced dual inlets with air baffles. A "Made In Canada" stamp has been recreated to further the authenticity and adds a nice touch to the black finish.  The exterior features a new reproduction Mopar licensed Air Cleaner Service Decal and passenger side vent tube. 

The lid features a gently used Mopar 340 Four Barrel pie pan (all discontinued) to augment the engine compartment, as well as a new lid seal. To complete the assembly, a high performance NOS perforated heavy duty air filter and period correct wing nut are included. A "Made in Canada" stamp has been added as a further level of authenticity. The wrinkle finish is nice - it features typical surface characteristics to match the factory finish. 

The 70-71 340 air cleaners are quickly becoming more difficult to find, as well as more expensive. Coupled with the depleted supply of Mopar pie pans makes a complete assembly that much more valuable.

As an added bonus, an OEM breather filter replete with OEM hose is included to make installation 100% complete. As an option, a 71 3 way breather is available if requested.

This assembly is in excellent condition and will enhance your restoration. Best of all, it is a genuine Mopar part!
