There is plenty of data that shows K&N filters do not provide the protection of an OE filter. If I drive my car through a whole tank of fuel and never see over 3500 RPM, why would I need more power (and less economy) than I already have.
The example I always remember is the 1.5 liter Alfa grand prix racer of 1950. Two .75 liter 4 cylinder engines bolted nose to nose with all accessories gear driven. 390 HP on 92cubic inches at close to 10k RPM. Two stage supercharging.
2 miles per gallon under racing conditions.
Power and economy is a great goal, but power means fuel and in the case of the Alfa a heck of a lot of fuel.
