Front oil cooler 

Porsche 911 to 1979

The 911 models from 1965 to 1979 were air-cooled, meaning they did not have a traditional liquid coolant system like modern cars. Instead, they relied on air-cooling and oil-cooling to regulate engine temperatures.

One common upgrade for these models is the addition of a front oil cooler, which helps to regulate oil temperatures and prevent overheating. There are many different types of oil coolers available, but the basic idea is to add a second radiator-like component to the front of the car to dissipate heat from the oil.
