Where did you get this 80% number?
Just fact finding.
This is just an observation based on 20yrs of servicing automobiles (yes, I was a certified mech).
All my servicing revolved imported (Japanese) vehicles with factory OEM thermostats (Japan made,some are sourced from Nippon Denso Jpn) typically outlasts any aftermarket thermostats commonly available here in Continental NA market.
Why ask? Conflict of interest going on? (you work for Stant or Motorad? or some domestic OEM supplier?)
*ball back into your court*
Q.
BTW: Stant has little to no presence in Asian manufacturing market (e.g. South Korea, Japan, etc.).
Stant was just the first manufacturer to come to mind. And if I worked for Stant, I would probably have more facts to ad to the conversation.
I'm not trying to go back and forth, or argue. Maybe your 100% right in your opinion on OEM thermostats being manufactured to a higher standard.
I've got a Civic with 220k miles on the original thermostat. But until I know for a fact that the "parts store" thermostats are made in an inferior way, I can't take a stand either way.
