One could install them a bit "away" from the exhaust pipe or muffler in order to reduce how much of the exhaust heat can get communicated to the TEG. Obviously any such idea reduces output and efficiency, but if it extended the life of the system significantly and reduced the need for more costly and complex coolant systems ... still... all this points to perhaps why it is not a common mod: kinda complex and fairly expensive without the certainty of being able to fully replace the alternator reliably. My alternator is nearly 20 years old and still kicking, on demand, cold engine or hot engine. If a $1000 TEG system burned-out after 4 years, I would be bummed-out!
See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
