Will K&N filter increase mpg?

A K&N air filter has the potential to slightly improve fuel efficiency (MPG) by allowing better airflow into the engine. This increased airflow can potentially enhance engine performance and lead to a minor increase in fuel economy, particularly during highway driving or at higher RPMs. However, the impact on fuel efficiency is typically minimal and may not be noticeable in everyday driving. To achieve significant fuel savings, it is important to combine the use of a K&N filter with other fuel-saving practices such as proper maintenance, driving habits, and maintaining appropriate tire pressure.
