Go with the 3M in the front and over the top of the doors I wish I had. I put the T-56 in mine which is nice on the highway cruisin. If you are going to put the
oil cooler put in a thermostat; the worst thing you can do for an engine is run with cold
oil. I love the look of the
oil cooler in Cobra but think the location is accident waiting to happen (rock or some other road debri). If I was going to put an oil cooler in for function only I would use engine coolant to oil type. Good luck Jay will do you right.
