OP, you do not need to do this at a dealer to get a quality product. You can have a qualified independent perform the service with an Aisin timing belt kit (they supply the original parts to the Honda Motor Co) for a lot less than a dealer is going to charge. The end result will be the same product for less.
After doing some research I found that AISIN is likely the supplier for the Subaru OEM thermostats so I ordered them off of Amazon (sold and shipped by Amazon) and they appear to be just that. They were close to the same price and are made in Japan. AISIN THF-007/009 appear to be true OEM Subaru thermostats for FB20B
Pick up the AISIN OEM version of your thermostat. It's pretty cheap so no reason not to get the best one instead of some cheaper alternative. Also you can test the function of your thermostat before doing the change by putting it in hot water. You can check the specs of the one you use, but for the AISIN one for my 2012 civic (9th gen), the thermostat starts opening at 170 and is fully open at 190.
I have used the aisen kits for almost a decade. They are very good quality & manufactured with high quality Japanese parts . Yes , they are more expensive. Make no mistake , aisen kits are the best timing kits you can buy
My impression was (recommended by many) this specific seller had everything OEM, water pump was the correct Aisin one.
Only use Aisin timing belt kits since they contain OEM high quality Japanese made parts.
RockAuto Aisin with the logos ground off. That’s when you know it’s the real deal.
Aisin only. It's the Oem.
Aisin TKF-005 has the 2 port pump and is otherwise identical to TKF-004 with the 3 port pump.
Aisin is of course the manufacturer of the defective one you are replacing. So there is that.
