GMC Sierra 2500 Performance Air Intake - K&N Engineering - 77 Series - `14-`15. A direct-fit K&N 77 Series performance intake designed to improve airflow and provide a durable, serviceable filtration solution for 2014–2015 Sierra 2500 applications.
This system uses a mandrel-bent aluminum intake tube paired with K&N’s washable, reusable High-Flow oiled cotton air filter to increase airflow while maintaining strong filtration. The oversized conical filter design is engineered to extend service intervals—up to 100,000 miles between filter services under normal highway driving conditions—and the included heat shield or airbox helps reduce intake air temperature from the engine bay. Typical installation can be completed in under 90 minutes with basic hand tools. Note: CARB/legal status can vary; check the product specifications for California compliance on your specific part.
