HIPO air cleaner ID help

[Jays66gt]

How can I tell if the air cleaner assembly on my GT is a HIPO?

It's got the chrome looking top and a blue base. I cannot see any markings.

Thanks,

Jay

Well its not the stock A code GT air cleaner.

Those are solid all around with a snorkel on the passenger side.

If it were original, I would expect it to have the original C5ZZ-9600-PG part number. Good chance it is simply a reproduction.

According to Bob Mannels "Mustang & Ford Small Block V-8" book, there should be a date code stamped in the air cleaner base plate (5A = Jan '65) and that the HiPo air cleaner for '66 was unchanged from the '65 design. Your picture looks like the correct air cleaner (maybe a repop with no date code?). Pictures in this book appear to have a painted (not chrome) base

I know it's not the correct unit. I wanted to know if the PO put on an original HIPO. I'll look for any date codes. Thanks

Looks exactly like mine, 20 bucks at the local Mustang shop

The 66 C5ZZ-9600-N air cleaner was a chrome top and Ford Corporate Blue base, and there was a connection for the crankcase breather in the base. Yours however, appears to be the cheap copy, not an original or good repro. A larger photo will help.

The 64-64 C5ZZ-9600-N had a gold base, and may or may not have the base connector. The chrome lid on the earlier version 64, early 65, had a very different "double ring" design.

All of my hi-po tops look like 22GT's car. I have a flatter on from my 65 K GT FB, but it's also quite heavy, as compared to the repros that are very light. There's no marks, but it does look like the later chrome top.
