Header wrap like this stuff from Thermotec (800.274.8437, is a great way to keep as much exhaust heat as possible flowing out the tailpipe instead of leaching into your engine compartment. The header wrap makes a good barrier, keeping the headers from radiating heat that might prematurely weaken your battery, alternator, electronic ignition, or any other component under the hood that would be better off at room temperature.
