Improved Blue CPS for 7.3L Ford Powerstroke Diesel
I did not author anything below, just cut/paste..
"International Part Number: IHC#1807339C92 This number has now superceded to an improved version, part number: 1885812C91"
"Original CPS for 97 & up F7TZ-12K073-A (black)
Equivalent Int'l part # 1825899C93 (black)
Recall CPS F7TZ-12K073-B (grey)
Equivalent Int'l part # 1876735C91 (grey)
Copied from another member's post:
Ford Black one (purpleish hue) for the 94 to 96 F4TZ-12K093-C replacing the 4C4Z-12K073-AB, price is 35.00 instead of 194.00 for the old one.
The old IH CPS number for the 97 and up is 1825899C93, it is now superceded by their new grey CPS for 26.00 bucks. 1821720C98 was for the 94 to 96, that is superceded by 1821720C99 which is a black CPS to but sells for 52.00.
I don't know that the 94-97 CPS was recalled, but the 97 & up definitely was.
The 1876735C91(/1876736C91) PN referenced above is the replacement (Gray) CPS for the IH 1821720C99 (Black) CPS. The 1821720C99 is the PN referenced in the OP as passing the CCT/PERDELS on an '02 F350 and is Made In USA.
There are still 400-ish of the 1821720C99 CPS's left in a warehouse in the PNW..."
