AISIN, TOYOTA PART WITHOUT THE PRICE
This is without a doubt, identical to the original equipment Toyota inlet housing/thermostat. AISIN manufatures many of the OE parts, these are identical in form, fit, and quality in an aftermarket affordable part.

OEM Aisin part
Came in an Aisin box, looks like an Aisin part and fits perfectly and functions properly.

Wow!! Truly impressed!!!
Well, this one took my breath away. Most people look @ the quality of their purchase. Aisin did not dissappoint. Wow, truly impressed the minute I opened up the box. This is very solidly built. I've replaced several of these throughout the years on different vehicles and they usually feel cheap and flimsy like they're not going to last you. Not this one, the plastic housing is solid and the thermostat and o-rings feel nice and sturdy as well. It has some weight to it, not too excessive though. Perfect fit on my 2010 tundra. This one is a keeper. Thanks Aisin for producing quality products. Definitely worth the cost and recommend. ... show more

Perfect fit like original one
Perfect fit like original one. So far so good after installed. Best price on Amazon

IMO No other option worth installing on Toyota vehicles.
Same manufacturer as OEM and a perfect fit and performance. My factory one is still working just fine but I'm going to replace it with the water pump. Like how the housing is painted from the factory. Another critical engine protection part that is not worth going cheap.

Good Product.
I would like to recommend this to anyone with a 2018 Tundra 5.7. Bottom nuit is hard to remove unless you remove the wiring harness next to it. Then all is good.

Go ahead and do the job right!
Complete your water pump or radiator replacement job with this! Fitment is spot on and so far after 3k miles not one issue! 2008 Toyota Tundra 5.7 4wd.
