Air filter

[ALLZS]

what is the correct style air filter for a 69 z28 flat hood car june build

[Mr70]

A212CW Filter that starts with BEST WAY TO PROTECT....

[ALLZS]

this is the one I have and got dinged for in correct air filter

[Mr70]

What was their reason and resolve?

[ALLZS]

they said it should be square cut at a 45 degrees also wrong choke pull off is there a straight and curved one where the vac hose goes ?

[1971ls6]

The straight one is for the later cars, my 71 vette used it, the diagonal is right for 69, don’t know about 70?

[ALLZS]

is anyone reproducing the correct style

[firstgenaddict]

69 Z should have curved tube on the choke pull off.

I had the diagonal 212CW on my old 69 Z... I know I researched the correct element for a while before deciding on the one to install.

AS an aside.

The NCRS judging guide states that the Square mesh chicken wire is correct up to April May of calendar year 1970.

As if the fire needed more fuel... I have seen photos taken for the 1970 Road tests by Karl Ludwigson which show 70 LT1 and 70 LS6.

The road test for the 1970 LT1 shows it with a 45 deg Diagonal woven soldered chicken wire -
The Road test for the 70 LS6 Chevelle shows an expanded metal 212CW. Car appears to be preproduction as there is a 9/20/69 date scrawled on the rad support.

here is my choke pulloff look correct

[Mr.Nickey Nova]

I always thought the square mesh was more for the Corvettes and the diagonal type for the rest??

[Mr.Nickey Nova]

here is my choke pulloff look correct
That's what mine looks like.

[1971ls6]

Go on the paragon corvette site and they show the horizontal for 70-72 and then they show the diagonal for the same years.

Diagonal for 69 is my guess, at least early 69

[Mr70]

I've an advertising photo taken in late fall 1969 of a Z/28 with an upright A212CW square mesh filter on it,but can't get it to post,and when I shrink it,the quality suffers.
I suppose it's a moot point anyway,as has been said,earlier cars seem to have had the diagonal square mesh,(turned on their bias),and later got the upright square mesh.
('69 camaros were made much later on into 1970 production year)

[ALLZS]

So what would you cansiter early & late production my car is a june built car

[x33rs]

Me personally I wouldn't consider a June car early at all. You're 2 months away from being a year into production and already past many of the revisions that happened throughout production. Just my thoughts. In my mind I can't really grasp why a judge would consider June early and ding you for an air filter.

There are several vintage road test photos of '69s that clearly show the element.

April '69 PHR has the same '69 Z/28 seen in Hot Rod and Sports Car Graphic. It was a production car built early October '68 at Van Nuys. Both it and the 396 Nova in the same issue have the 45º square mesh.

One of the more famous Z/28s is the yellow/yellow JL8 car that was featured on the cover of the August '69 Car Life. They tested it with a cross-ram and fiberglass hood. However, Road Test featured it in their August '69 issue, pre-cross-ram. The combination of JL8 and yellow houndstooth means the earliest it could have been built was very late February. Don't know anything else about it.

Here's the engine bay pic.

That car was what put me on the hunt for a yellow/yellow car....Joe

Any more input on these filters?
Just my .02 cents worth
I’m thinking pre ‘68 OEM were Embossed
Then OEM and over the counter were stamped
“ Best Way to Protect Your Engine -Replace with AC Type A212CW”
What I’m not sure of are when the wire design changes were maid.
You have the
“Welded chicken Wire” Square Mesh then,
“ Welded Chicken Wire” Square Mesh tilted at 45 deg. then,
The “ Expaned Metal” tilted at 45 deg.
Then some time in early 1970’s they got away from
“Best Way To”
And just left
“Protect your Engine with AC Type A212CW”
And later with just
“A212CW”
I have collected these for years and
will be listing in the for sale ads so keep an eye out.
The other question is
How many AC Plants made these and where were they located?
Did St.Louis , Norwood, Baltimore etc. recieve product from an East Coast plant.
And the California plants another?
This is a great source of info here and I’m surprised this thread isn’t a lot older.
Even on the Corvette sites not much at all.
Thanks SYC!!

I just noticed... :scholar:
The REPRODUCTION "chicken wire" does not have the "wires" over - under - over - under... ***ALL the verticals are over and ALL the horizontals are under.***
The originals are actually WOVEN.
