Cooler air induction vs the HEAT WAVE.

In AZ I've run my car in 120 degree ambient temps with no problems. Would you pull the air filter off of your modern car? I didn't think so...

But my modern car (Fusion) pulls air from in front of the radiator, not inches from the exhaust down pipe, and with modern FI you don't have a fuel bowl percolating on a hot engine.

On cars with cowl induction or hood scoops you are getting higher pressure and (relatively) cooler air than the rather stilted air under the "A's" hood. I've noticed that since reinstalling the splash guards alongside the oil pan the radiator runs cooler but the firewall is hotter. Where the air could rush out under the engine, now it s trapped around the block, and right at the air intake.

I'm going to try it to see if I can get a little of the "rainy day in Octber" power back.
