Not much of a study. Its a part with a brand name driving high $$$.

Meanwhile, someone is giggling all the way to the deposit slot at the bank.
There are other brand out there made in china

If you are phobic about where a product is made, then be sure to read the Country of Origin label.
Do you have a cell phone? Care to guess it's Country of Origin. TV? Computer? Refrigerator? Washer? Dryer? Power Tools? Hand tools?
How do you know the Country of Origin for the Toyota part? Japan? China? Tiawan? Viet Nam? India? Thailand?
Toyota has factories scattered throughout the world.
Trust me, I've had some grade A c-rap made here in the USA.
I've bought replacement carburetors made in china for my small stihl power equipment that have outperformed, and outlasted the original carbs made here in the u.s., or mexico for a 1/3 of the cost. Not everything made here in the old usa is good....we just charge more for our junk.
