"The standard OEM Honda part number follows a format of xxxxx-111-xxx.
If the part is painted, the part number has an additional two digits to represent the paint code, ie xxxxx-111-xxxzz. If the part is something a dealer would purchase in bulk, like hose or bolts, and it fits many models from different product lines like motorcycles, ATVs and generators, the number format is xxxxx-xxxxx-xx.
Honda Product Code - The centre section of a standard Honda part number contains 3 digits (111 in the example). These 3 digits are the Honda Product Code and correspond to the Honda car, motorcycle, scooter, ATC or ATV model that the part is for or was first used on."
SAA certainly corresponds to Mk1/GD Jazz. Different OEM suppliers can mean variations in the code, updated/uprated parts will also have a new code even though they are compatible fitment. The trade parts counter (not via the showroom) at the dealer will be invaluable here if you provide your VIN number. You have probably discovered that the part listings from a 2006 vehicle give the codes you are stating. I can't imagine a variation between 1.2/1.4 or CVT/manual.
Will investigate.
