The K&N Performance Air Intake System fits the 2020-2026 GMC Sierra 3500HD 6.6L V8 and delivers a guaranteed increase in horsepower and torque over the factory airbox.

Bolts to factory intake mounting points with hand tools and reuses the OEM MAF sensor; typically installs in 45-60 minutes.

Product Overview

This cold air intake replaces the restrictive stock intake with a mandrel-bent aluminum intake tube for smoother, higher-volume airflow to the 6.6L V8.

The system includes a washable, reusable K&N High-Flow Air Filter with oiled cotton filter media, designed to be serviced instead of replaced.

For 2500/3500 HD owners, that means more usable power for towing and hauling, plus a long-term filter that eliminates repeat cartridge purchases.
