1970 Chevrolet Chevelle/El Camino SS LS3 396 LS5 454 Z15 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 with the notched center seam 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 licensed reproduction Air Cleaner Service Decal (DG). It is also unique to this year as well, incorporating the new for 70 ribbed base with periodic reliefs in the rib (aftermarket pieces don't have them). The flame arrestor tube is topped with a dimpled replacement stainless screen, all connected to the valve cover with a GM yellow stamped adapter hose on the bottom connector tube. An original style date stamp (late 69) has been added for further authenticity and as a nice finishing touch.  

The original cowl seal flange features the stamp and fitted with a new seal along 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 choice of either a GM licensed 454/450HP or 396/325HP 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.

The aftermarket has supported this particular style of air cleaner, but when looking at details, comes up very short. Notably, the snorkel is incorrectly welded to the base and is missing the notch in the seam; there are no indentation reliefs on the air filter ridge; discernible differences in the distributor relief; missing the W in the seal flange.

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

454/450 & 396/325HP 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.
