The K&N Performance Air Intake System fits the 2020-2026 GMC Sierra 2500HD 6.6L V8 and delivers a guaranteed increase in horsepower and torque over the factory airbox.
Product Overview
This cold air intake replaces the restrictive stock intake tract with a mandrel-bent aluminum intake tube for smoother, higher-volume airflow to the 6.6L V8.
The system pairs with a washable, reusable K&N High-Flow Air Filter using oiled cotton filter media, so it cleans instead of replaces.
The result is stronger throttle response and a more aggressive intake note on the Sierra 2500HD.
