Oh, I see what you're referring to now... UPC code K45, HD Dual Stage Air Cleaner. This was just a heavy duty element with additional oiled foam around the paper element.

Here's a photo of the HD instruction label from one of my old '69 GP's.

It was listed under sale code 731 UPC K45 as "Air Cleaner Dual Stage HD $9.48" I've seen at least half a dozen Grand Prix PHS's over the last few years the have it listed. The few I've seen this one had the dual snorkel air cleaner, maybe the owners added it then? They sure look better than singles that's for sure.

----The K45 dual stage air-cleaner was included in the Y88 basic group which is probably why we have seen quite a few on 69 GP's. My 69 has the Y88 option with the dual snorkel!.....Bill S

Can I have it ?

Bill... K45/731 had nothing to do with a dual snorkel air cleaner, it was the element only as I mentioned above and could be had with either the small single snorkel 400 air cleaner or the larger single snorkel used on 428 engines. Not to say that the factory "never" installed a dual snorkel or one slipped through on a '69 GP. Here's a few more photos of the Model J 400 that I referenced above.

Me first!

I'd take it too, but I'd rather have Scott's Espresso Brown SJ.

Yep, hard to beat a 13K mile survivor with three pedals.

Quite the pair...

Great shots, thanks for posting them Grant.
