It's going to get hot anyhow. Actually there is a difference. Try painting your firewall black and experience the difference. (Even under the dark cowling). Three items are critical for colors under the cowl, (we are working with an engine that has a tendency to run hot and can use all the performance enhancements available. Besides it don't cost much, so do it): Intake Air and Gas, (Intake spider, tubes, etc): Should be White, thick coat. This helps keep the gas and air temp down and results in better performance. (Don't paint the air filter area white. With carb ice problems, it could hurt, but probably won't). Engine and Oil Slump (Including Oil Cooler and mags.): Should be black, one coat of very thin high temp. This helps transfer heat to the cooling air as it is pass from the high pressure area to the low area. Also air is blowing on the oil slump from the front onto a black oil slump. If you have a oil filter, paint it black before installing. (A black prop may give a little help. The prop acts as a radiator, to some degree, and transfers heat from the crank to the air). Exhaust: White thick coat. This is to reflect the hot exhaust back into the stack and take it out of the cowl. Now I'm not saying you will see a large drop but you may get a 5 - 10 degree drop on a normal day. If you are always pushing the max on temp then it may give a little edge. And why not - paint is cheap, overheated engines are expensive. "Take care of the pennies and the dollars will take care of themselves."
