Definitely some old posts back to 2009. But Good Alternative options mentioned here for air filters. Especially given it will never be seen inside the plenum. CP is a great Conversation piece anytime the hood is open :)

I believe Steve closed his business about a year ago.

Steve's Camaro's (Steve Pardini) closed his business as Warren stated.

I tried Heartbeat's and it's the same as the parts stores AC Delco A697C 8997189. It's roughly 7/16 too tall. Didn't take it back and couldn't locate anything that would work so cut it down and used windshield urethane to bond the rubber seal down to the element. Actually works and looks good but rather spend an hour elsewhere.

May I ask what you tried it in? Meaning a Chevelle unit. Or Camaro??

The Chevelle unit and Camaro unit both use the same A226CW filter. The cowl plenum shown in your post at the top of this page appears to be a repro which uses the more commonly available 17" diameter lid. It has a rubber seal in the outer groove whereas the real cowl plenum lid is 16-3/4" in diameter and does not have a rubber strip for sealing to the base. The "697' filter will fit with the larger diameter lid because it was designed to use that filter in the first place. The larger diameter lid is used for the repro because it looks close enough that most people don't catch it, uses a commonly available filter, and means there is one less piece to have to tool up to get made.

Yes- Correct

I "JUST" tried a New ACDELCO A697X in My NKR Camaro CP (Cowl Plenum) unit with a 16-3/4" diameter lid without any rubber gasket designed and the New filter was to tall. (Bummer)

NKR supplied a WIX 46948R with a rubber compression tube glued to the bottom.

It's on a Chevelle. Tried the Wix 46948R but it's too short but might use it next time with a spacer.
