1970 Chevrolet Chevelle/El Camino/Nova SS L34 396 LS3 402 LS5 454 Z15 ZL2 Reproduction Cowl Induction Air Cleaner. This assembly has been reworked and refinished in the correct semi-gloss black finish to present a period correct image. The single snorkel with round end is in very good condition and correct for the one year only style LS-engined Cowl Induction platforms. The base is very clean and adorned with a GM reproduction Air Cleaner Service Decal (DG). It is also unique to this year as well, incorporating the new for 70 ribbed base with 3 periodic reliefs in the element rib. The flame arrestor tube is topped with an NOS GM stamped dimpled stainless steel screen, all connected to the valve cover breather tube. An original style date stamp (late 69) has been added for further authenticity as a nice finishing touch.   

The original cowl seal flange features the notched edge (HVAC clearance) and an original survivor seal, completed with a new REAR decal. An original black cowl lid enhances the classic muscle car appearance and sits atop a new heavy duty air filter. To add further distinction, a GM licensed 396/375HP Turbo-Jet decals are included and complements the overall assembly. To complete the package, a period correct wing nut is included.  

As an added bonus, the assembly comes with the correct air cleaner spacer and an NOS GM Valve Cover 90 degree elbow.

This assembly is in excellent condition and will enhance your restoration.

This part is an aftermarket piece that has variations from original pieces – all out of sight once installed, but mentioned for clarity. Notably, the snorkel is missing the notch in the seam;  fewer impressions in the distributor relief; missing the W in the seal flange.  We have reworked it to make it as aesthetically correct appearance-wise, but with a more cost effective price point. We rarely offer reproduction pieces due to the nature of our business, but there are times when either original parts are made of unobtanium or simply cost too much. We are confident that most onlookers will not be able to discern the differences mentioned above without taking the unit apart. 

Many of our parts are available only once - we cannot predict if/when another will become available due to the scarcity of original parts. The old adage "here today, gone tomorrow" applies to many of these unique assemblies. While we strive to maintain a strong diversity of desirable parts, there simply aren't enough available to meet demand at times.

This assembly is correct for the following:

1970 Chevrolet

396/402/454 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 same style air cleaner for this year only. 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 1971-72 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.

Note that this assembly will also fit the 69 Camaro cowl induction set-up as well; primary differences are the tapered cut on the cowl seal flange and the ribs in the bottom (original 69 assemblies featured neither of these revisions).


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.



The assembly will ship within one day (usually the day of payment) with shipping/tracking information provided.
