It there a difference between the air cleaner used on these cars and the one used on 70-72 Z28s? If so, can anyone tell me what it is?


Thanks,

I was just looking at that today and wondering the same thing,
I really hope some one can answer this one

Yes, there are a few differences. That's why the price on the real ones get steep.

First, take a look or feel the bottom. It should be flat/smooth. Take a look at these 2 pictures.

wrong- note the ridge in the bottom; even while it's on a car you can reach under and feel this ridge/groove



correct- note the flat bottom; no ridge/groove; take note on the part number #6421970 and the correct location of service decal, pass. side



Now for the more obvious wrong thing without having to touch it.

wrong-the way the snorkels are mounted is different; these have a mounting flange that's on the outside of the air cleaner body
See the way the snorkel meets the body on this one?



here's how it should mount and look



It shouldn't have a service decal in between the snorkels that says "Front" on it. The top was not chrome. It was painted black just like the rest of the air cleaner.

I just posted an air cleaner for one of these cars on Ebay. I thought a few of you may be interested. Here is a link: 66 Air Cleaner

Good Luck,

Does anyone know the part number for the air filter element that goes in this air cleaner?

Thanks,

That used the very popular AC-Delco A212CW element.
Chevrolet recognizes it as #6421746.
