I'm Awesome
Even without the headers, I had noticed that the engine bay got really hot when towing. Then I realized that there is no outside air flow into the engine bay so heat just builds up. So I removed the rubberized splash guards from the wheel wells and the brush/rock guard from the front under the radiator. We never go off road, so don't think I need it. When the rain starts up here in the rainy Pacific NW, I'll put the splash guards back on. Weather is much cooler anyway at that time. The couple of times I have driven it on warm days the engine compartment is much cooler when I pop the hood with the splash guards gone.
