P30 chassis attachments to frame and spark plug wire issues

I made air dams out of FG sheets to force the grill air to flow through the AC condenser and radiator. A friend of mine made an air deflector with a steel plate that was 4-6 ins lower in the front of the grill that would scoop the air and force it into the radiator. He said it had a huge effect on lowering the eng temps. I think anything that you can do to make the air goe through and not under or around your radiater will help.
