You will find many people that will claim that the K&N filters have given them all kinds of benefits. All I have to say is, if someone goes out and spends that kind of $ to increase their HP and MPG, they are going to feel pretty stupid if it doesn't work. They are pretty invested in having a positive outcome, so they have one. I am not saying that they are being untruthful, I am merely saying that "they are pretty invested in having a positive outcome".

It is nearly impossible to evaluate MPG and HP when driving a vehicle. This is especially true when you are talking about ranges of 10%. There are a hundred different things that could account for a 10% increase or decrease in MPG on any given day or over the same piece of ground. As far as "Feeling" a 10% increase in HP......... fiction....... 10% is imperceptible without the proper equipment.

In many cases the mere difference in sound that the K&N system emits, gives the driver a "sense" of power.
