Not true, a completely plugged air filter will result in 0 MPG, as in the engine will no longer run.

If it is removed it will result in the same 0 MPG from the engine dieing of sludge.

dirty air filter

I thought that ICE is an air pump and if it has to work harder to suck air through it will take a little more energy to accomplish this. apparently not a lot.

The throttle plate is still the biggest restriction unless you floor it, which is why there's a reduction in peak power.

Huh?

The article studied putting show towels over the air filters to simulate a plugged filter to see the effect on MPG. In the real world the filter will either eventually become completely plugged so the engine will no longer run, or the filter will collapse under the vacuum and the engine will slowly fill up with dirt until it no longer runs. Both will result in 0 MPG.

I have seen both, the filter plugging is the easiest fix. Working on a sludge engine is horrible.

If you are saying that this studies says your Otto cycle internal combustion engine no longer needs oxygen to burn fuel then you had better reread the study yourself.

I to have thought that a restricted intake would increase mpg , I think that's why my vw tdi gets such great mileage, it has 225,000km on it and the 1.9 tdi is notorious for clogging its intake from the EGR.
In effect lowering the cars hp and subsequently the fuel consumption as the cars computer always maintain a clean burn threw the fuel injectors.

I expect when and if I clean my intakes filth out my hp will increase and economy will decrease, unless i can drive like a saint 100% of the time.

But Diesels tend to run leaner, so the clogging at the intake might make it just roll a little more coal instead of improving the fuel-efficiency, plus at a certain point you'd have to keep the RPM higher to get a certain amount of power...
