I agree with Bob,
The
oil cooler is part of the original cobra equipment and look and I think they look great, but you don't have to hook it up. I will be racing my car and it maybe only on a hot summers day the cooler is necessary. The downside to coolers on cobras in original position is vulnerability if you rear end someone, stones so a gauze screen is really necessary...
I purchased a Canton
oil thermostat and living in a colder climate NZ I don't believe this is all necessary so have decided to bypass the cooler with a joiner fitting, and if I am doing a longer race I will plumb the cooler in.
So it depends on if your engine is producing big horsepower and you continually use that either on some open highway, fast hilly area or race then the heat is going to increase real quick, I have over 650bhp 373 Ford and hp equals energy/heat...
