NOS Cowl Plenum on ebay
 

Just happen to see this:

I believe that is a 1967 Camaro unit since it has only one indent for the distributor. The 1968 unit would have two indents for distributor and air pump.

Air Filter Element alone is worth some $$

Has anyone ever reproduced these in the past?
They look so trick under the hood and doesn't seem to be too difficult to make a high-quality one. Just curious- because you rarely see this on a car in person.

Yes, they are being reproduced.

The reproductions are fiberglass, not steel.

The bottoms are steel; the housing, lid and plenum duct are fiberglass.

They have been reproduced in Both.

NKR Products:
Steel: Nelson Rudisill 828-874-2335 6-930 PM EST source for ALL steel VERY high quality.

I have a NKR 68 camaro version and It is of High Build Quality. Repeat ALL Steel!

Do the reproduced ones use the same filter element? Have an original and can't find a filter to fit.
