What are some effects of an air filter not changed in a 04 powerstroke f250?

Answer 1

All engines are developed to produce a certain amount of horsepower based on their physical characteristics. The most important features of an engine that effect power are the number of cylinders, the cubic displacement, valve layout and the delivery of air and fuel.

Air is a necessary ingredient to the combustion process of an engine and the more air molecules the better. The job of an air filter is to significantly reduce the amount of dust entering an engine while providing adequate airflow for the combustion process.

As an air filter accumulates dust, its ability to flow air will eventually decrease. This is true for all filters regardless of type. That is why a dirty air filter can degrade gas mileage or cause a vehicle to become sluggish

There is a direct relationship between airflow restriction and mileage. The theory behind this is simple, the harder an engine has to work to suck air through the intake tract and air filter, the more gas gets wasted in the process.

This impact is so dramatic that a clogged air filter can reduce mileage by as much as 10%. This is a number published by the US Government. Often, this decrease in mileage is not noticeable because it happens slowly and over time, but it adds up.

10% is HUGE, with the price of gas it's easy to see how important and valuable it would be to reduce the amount of time spent driving a vehicle experiencing a shortage of air.

(i.e Reduced MPG & Loss of Horse Power).

Hope This Helps.
