The red box: ~$130. and 1 year, unlimited miles warranty, limited labor coverage as well.
The blue box: $58.79 from Rockauto, 12 months/12,000 miles warranty.
I have never had the chance to test the warranty on any Aisin or for that matter Denso parts, they have always worked. But have on other brands and have had great results with Rockauto standing behind their products.
Examining both, IMHO, the biggest difference is box color. Have replaced a couple of 1FZ water pumps, but haven't seen a bad/failed one and several that we work on are in the ~300k mile range. So, if you are burning cash replacing it as "PM", likely best to burn as much cash as possible?
My guess: Aisin makes a large production run of 1FZ pumps, Toyota commits to a quantity of them and those go into the red boxes. The rest get the Toyota ID ground off, go into blue boxes and are sold through the wholesale network. The wholesale network is likely much more efficient, works on a lower margin, they don't need to support taj mahal type buildings, massage chairs, coffee counters, barber shops, car washes, etc, that dealers do.
