Leland I think you should go with just the Mocal, that should be enough for anything you will be running with your SC. Jack needed more due to the large HP, Big engine. I think one cooler on your 3.0 should be lots. And you don't want to put Carrera stuff on your SC. Get rid of it, get it as far away as possible- Say Canada or someplace- I know a guy who would get rid of it for you up here
Seriously I think one will do for your car though Leland
GET HOME! And start putting these things in your car.
