17- GM P/U 2500 6.6L Air Filter

The K&N Engineering 17-GM P/U 2500 6.6L air filter is purpose-built for heavy-duty Duramax diesel applications, delivering superior engine protection and airflow compared to stock paper filters. Designed for full-size GM pickup owners who demand reliability under demanding conditions, this reusable cotton panel filter addresses the core challenge facing diesel enthusiasts: balancing filtration efficiency with sustained intake flow. Whether you're towing, hauling, or operating in dusty environments, a quality air filter element directly impacts engine longevity and performance consistency.

This filter element features K&N's signature oiled cotton media construction, which captures contaminants while maintaining lower restriction than conventional disposable filters—a critical advantage for naturally aspirated and turbocharged Duramax powerplants seeking maximum fuel economy and response. The 11 x 10.938 x 2.25 inch panel design fits the factory air box without modification, ensuring seamless integration into your 2017-and-later GM P/U 2500's intake system. K&N's reusable design means you clean and re-oil this filter rather than discarding it, reducing maintenance costs over the vehicle's service life while minimizing environmental waste.

Fleet operators, diesel enthusiasts, and truck builders running the 6.6L Duramax benefit most from this upgrade, particularly those operating in high-dust conditions or maximizing towing capability. Installation requires no fabrication—simply remove the factory element and drop in the K&N filter using the existing frame. Compatibility is confirmed for full-size GM trucks with the Duramax engine, making this a bolt-on refresh that improves airflow dynamics without sacrificing protection or altering your truck's emissions compliance.
