Aisin is Toyota and OEM Match
$250 cheaper than the same "Toyota" part from Toyota. Aisin is owned by Toyota so this is an EXACT OEM match.

Working great still
Installed a few months ago on a 2012 Prius C3. The old one seemed intermittent and low flow. This one installed pretty easy watching a YouTube video and is working very well still. Great price!

Replaced on my 2014 Toyota Prius Plug-In
This was an exact match to the OEM Inverter Cooler Pump that I removed from my 2014 Toyota Prius Plug-In. The Toyota part number on this box and manufacturer is the same as the OEM one that was removed, even though Toyota's part number is not stamped on the pump itself. I replaced it pre-emptively at 163K via the underside panel while changing inverter fluid out. Look at priuschat to find out how to do this without removing, or even moving the inverter. Hint, A rachet with a 9" ext on the tool and another 6" ext on the 10mm hex will get the 1 bolt from the top. The other 2 bolts are accessed from the bottom anyway.

Works perfect
A bit difficult to install but works perfect. I probably installed it the hard way. I believe you can unscrew one bolt on top and then there’s 2 bolts underneath to remove. I removed the inverter to give me more room but I’m not sure that was necessary. Not bad overall. Fairly straight forward install. Just lots of bolts to remove if you do it the way I did
