Put your hand on the exhaust manifold and get someone to start the car. You'll see how quickly it heats up. Also use an obd II scanner and check IAT's and you'll be able to quantify the difference.

Is it significant enough to cause a large reduction in fuel, not likely but there will be a measurable difference in intake air temps
I like to drive a slow car fast...

I tightened down the flange at the manifold better, I saw that my IAT was up in the 80s now, the weather was in the 40s.
