Replacing your OEM air filter with a drop-in air filter is a great way to increase airflow without replacing your entire air intake system. Replacing your air filter is cheap, fast, and easy. Another benefit of replacing your OEM filter with a drop-in filter is that you can wash your drop-in filter. You will never have to replace your OEM filter again.
