Premium Air Filter AF25169 P636070 for Paccar Engines

The AF25169 P636070 air filter is a high-efficiency replacement designed for heavy-duty diesel engines used in Paccar-powered trucks and Peterbilt vehicles. Built to meet OEM filtration standards, it ensures clean airflow into the engine by effectively capturing dust, dirt, soot, and other airborne contaminants.

Clean air is essential for optimal combustion efficiency and engine protection. In heavy-duty trucking applications, poor air filtration can lead to reduced engine power, increased fuel consumption, and accelerated engine wear. This air filter helps maintain stable airflow and supports long-term engine reliability under demanding operating conditions.

With a height of 14.46 inches and precision-engineered filter media, this air filter provides excellent dust-holding capacity while maintaining low airflow restriction, making it suitable for long-haul and vocational trucking applications.
