Indeed they did , a special coating on the radiator reacted with the heat to clean the air somehow , It was a token really , it couldn't possibly be measured with the roadside equipment we had today , The catalylic converter they pioneered 3 or 4 years before it was a legal requirement has made a big difference though .
