This panel air filter will increase airflow through the intake system by reducing the restriction of the air filter element. By doing this you allow for a more dense air charge which in turn leads to more fuel being injected and results in more horsepower. This is an easy way to free up a few extra horsepower without breaking the bank and includes a feature often overlooked in panels filters: re-usability. This may be the last filter you ever need to buy since you simply need to use the recommended filter cleaner and oil and the filter is like new again. Sold individually Washable and re-usable Filter cleaner and oil sold separately.
