My old warped OEM radiator fans way past their replacement.
I've been thinking of getting aluminium ones instead of going back to stock. Only brand I have in mind is Muzzy and they don't seem to stock for the Vtec.
Fans are one of those parts that sometimes differ from one another only by the mounting brackets. Different mounting bracket=different Honda part number, but the fan motor is often the same. Unfortunately, the only way to know for sure is to have access to a bunch of different OEM fans, or know that someone else has swapped a particular one for another. Can't help you there, sorry!
