Only oil in dusty environments and use a quality cleaning and oil kit, following instructions to avoid over - oiling. - **Pre - filter**: A pre - filter keeps large debris out, making maintenance easier.

Using this Pusher Hollow Point Air Filter is easy. Just install it in your compatible Cummins, Duramax, or Powerstroke engine according to the provided dimensions. Make sure to check it every 5,000 - 6,000 miles, preferably when you change the oil. Take it out and tap off any loose dirt, bugs, or debris. If it looks really dirty, it's time for a full wash. In normal driving conditions, clean the filter every 30,000 miles. But if you're driving in a dusty area, you'll need to clean it more often. And you might also need to oil the filter media in dusty environments, but only use a good - quality cleaning and oil kit and follow the instructions carefully to avoid over - oiling. A pre - filter is a great addition as it keeps large stuff like bugs and rocks out of the filter, making maintenance a breeze. Pusher's pre - filter also helps keep the filter dry. Keep an eye on the filter media. If it starts to look frayed or wrinkled, it's probably time to swap in a new filter. On average, you'll need a new one after 2 - 3 years of use.
