We put in a k&N filter removed almost all the AC stuff on are w116 and where just getting ready to put an aircraft tow vehicle battery in the trunk it is about 3 times the size of a diesel battery and powers KC delighters very well including the one behind the rear license plate. We were also about to install an electric fan when I wrecked the car. I took the ac pump out of my w115 to make repairs and I would not put that sob back in for all the gold in china of coerce 90 degrees is a bloody crisis here in the land of 75 degree days
