1971-72 Chevrolet Chevelle SS 396 454 Cowl Induction Air Cleaner
1971-72 Chevrolet Chevelle/El Camino SS LS3 396 LS5 454 400 ZL2 Cowl Induction Air Cleaner. This assembly has been refinished in the correct semi-gloss black finish to present a period correct image. The single snorkel with round end is in good condition and correct for the last of the LS-engined Cowl Induction platforms. The base is very clean and adorned with a GM licensed reproduction Air Cleaner Service Decal (DG). Note that the snorkel is canted downward and is angled towards the corner of the passenger side fender (71-72 specific). It is also unique to these years as well, incorporating the ThermAC pre-heater function that was required for the new emissions standards of 71. The flame arrestor tube is topped with an original GM stamped flame arrestor screen, all connected to the valve cover with a GM yellow stamped adapter hose on the bottom connector tube and includes a newer 90 degree valve cover elbow. The ThermAC connects to the AC Air Temperature Sensor with new white-striped vacuum hose and is secured with an original GM clip. An original style date stamp has been added for further authenticity and as a nice finishing touch. A nice original pre-heater elbow, replete with Wittek clamp and new aluminum pre-heater tube, is included to make installation more complete.
The original cowl induction flange is fitted with the original seal (you may choose to replace it, or use as is - it is loosely installed) and new REAR decal. The original cowl lid enhances the classic musclecar appearance and sits atop a new heavy duty air filter. To add further distinction, a choice of either a GM licensed 454/365HP or 396/300HP Turbo-Jet decals are included (temporarily installed - permanent installation to be made by the buyer as required) and complements the overall assembly. Please add a note to seller with your choice at checkout. To complete the package, a period correct wing nut is included.
This assembly is in excellent condition and will enhance your restoration. Best of all, it is a very rare and genuine GM part.
Many companies will try to pass off the 70 style reproduction cowl assembly as correct for 71-72 models - this is not the case. These were specifically designed to meet more stringent drive-by noise regulations, as well as be emissions compliant. While the aftermarket pieces are "affordable," they are far from correct and can be distinguished from originals in 2 seconds when one knows what to look for.

This assembly is correct for the following:
454/365 & 396/300HP & 400/300HP Turbo-Jet models installed in Chevelle SS/El Camino SS cars featuring the Cowl Induction ZL2 option.
Note: both automatic and 4 speed equipped cars featured the ThermAC valve on the top of the snorkel. Non-cowl induction cars used a smaller case single/dual snorkel air cleaner specific to these years depending upon the A/C option. These assemblies differed from the 1970 version with the incorporation of the new for 71 ThermAC emissions provision for heated air at start-up using the air temperature sensor. The snorkel was canted downward, as opposed to the 70 straight version.
The assembly will fit factory 4 barrel Quadrajet carburetors with a 5 1/8" diameter flange, as well as Holley (factory), Carter, and Edelbrock variations without electric choke (some adjustment to the carburetor alignment tangs may be required). If you have modified your carburetor or intake manifold, please inquire first prior to bidding to ensure fitment is correct. Return requests for non-fitment will not be honored.
