Performance Cold Air Intake Kit for GMC Sierra 2500HD/3500 (6.6L V8 Diesel Engine)

Your GMC Sierra’s stock air intake system, while functional, acts as a significant bottleneck, choking the powerful 6.6L Duramax LB7 engine. The factory airbox and corrugated intake tube restrict airflow, elevate intake air temperatures, and hinder your truck’s ability to breathe freely, especially under load when towing or hauling.

This Cold Air Intake Kit is meticulously engineered to eliminate these factory restrictions, delivering a direct and unobstructed path for cool, dense air to reach your engine. By replacing the inefficient OEM components with a high-flow aluminum pipe and a superior washable filter, this upgrade optimizes combustion efficiency, significantly boosting your Sierra’s horsepower, torque, and throttle response.

Why You Need This Upgrade

• Unleash Horsepower & Torque: Unlock impressive gains of up to 10% in both horsepower and torque, providing your Duramax with the extra muscle needed for demanding tasks and exhilarating daily driving.
• Sharpened Throttle Response: Eliminate turbo lag and enjoy a more immediate and agile feel from the moment you press the accelerator, transforming your driving experience.
• Premium T304 Aluminum Construction: Crafted from lightweight, high-grade T304 aluminum, the intake piping ensures optimal air velocity, superior durability, and excellent heat dissipation for consistently cooler air.
• Exceptional Filtration & Airflow: Engineered with an advanced, high-flow conical filter that maximizes clean air delivery while effectively capturing harmful contaminants, protecting your valuable diesel engine.
• Aggressive Diesel Engine Note: Experience a more pronounced, deeper engine sound under acceleration, giving your Sierra 2500HD/3500 a powerful and sporty presence on the road.
• Long-Lasting Washable Filter: The reusable and washable air filter extends service intervals up to 50,000 miles under normal driving conditions, saving you money on disposable filters and maintenance.
