Pre Catalytic Converter

Post by GripGreg »

Guys, I'm drawing a blank. What is the name of the system used before the catalytic converter, that over heated the head??? :roll: :oops:
You'll say it & I'll say, "Of course, I knew that! I just couldn't think of it".
Still a blank! :? Was the'79 the last year or the '78??? :?

BMWs name was Thermo Reactor.

After finding how hot it made her first E21 run my wife took to calling them nuclear reactors. :D

Model year 78 was the last of them in E12s, in other BMWs of the era, Es 21, 23 and 24, 79 was the last year. E12s obviously got cats a year earlier for some reason.
