You could do the same and provide evidence instead of having none and attacking mine.
Who's contradicting themselves?
Also, removing the air filter? Anyone with half a brain knows that the particles getting into the engine from that would ruin it.
If you actually read my post, you would have understood what when I said cooler, it means relative to blocking the air intakes into the engine compartment and the vents underneath such with a full belly pan.
As I said, and I'll repeat, all engines have an optimum operating temparature, and it varies from engine to engine. There is no definite number for all engines, and it's asanine to think so.
And I'll repeat again, try overheating your engine constantly and see how long it lasts.

Gains all across the powerband, but more noticeable at high RPMs.
I'll lay it in common sense that even an elementary student can understand:
For gas to blow up, it needs oxygen. When air is cold, it's dense, meaning there's more in it for a given space. If cold air goes into an engine, there's more oxygen to blow up the gas. This makes sure there's a bigger boom. Bigger boom means more power.
Clear enough?
