Air Intake Mods

I agree that no real gain in pressure however here is the gains
Let's assume the factory airbox with its inlet behind the headlights draws in 70F air. A modified car with an exposed cone filter might breathe 110F warm air under the hood. Comparing the difference in air density with these two conditions reveals the warm air is 7.5% less dense than the cooler air and would consequently reduce engine power by a similar percentage - 158-hp vs 170-hp - a 12-hp reduction!

Maybe I'm not quite right
I want to make sure it is dryed and then oiled properly before putting it back on. In the mean time I wanted something to run so I got a BHAF. I wish there were other options. Having the filter dry and evenly distributed oil are issues. I wish there were a paper filter that I could slip an outerwears on while I'm fussing with the Uni. Am I being overly cautious?

Ok...I understand now.
Yeah, I doubt very much that there is a paper filter you can get to fit into the Scotty intake.
I would think after washing - drying would take the most time. After its dry you should be able to oil it and you should be good to go in no time.

years ago when my trailers were loaded heavier and they had less hp i thought they were a lot doggier in the hot days of summer.....
i yield to the pros on this stuff.
no arguement here......

I am by no means an expert, but I do recall from science class in HS that warmer air compresses differently than cold air, so common reasoning would say cooler air will have a differing effect on engine performance as compared to warmer air. And since warmer air is actually expanded apart more, density wise it should mean that it will take MORE warm air for the engine to use during combustion to achieve the same result as it would with cooler air.

Air/Fuel (A/F) Guage
If outside temperatures are low, your engine will run leaner than if the outside temperatures are high.
