Cold Air Intake for Chevy Silverado 2500HD 3500 (2001-2003) 6.6L Diesel Engine - Blue

Performance Cold Air Intake System with Heat Shield for 2001–2003 Silverado 2500HD/3500 6.6L Duramax Diesel

Your Silverado HD was built to work—hauling heavy loads, towing trailers, and conquering long highway miles without breaking a sweat. The legendary Duramax 6.6L diesel under your hood has the strength to handle it all, but the factory intake system holds it back. This precision-engineered cold air intake with integrated heat shield unleashes the full potential of your heavy-duty workhorse, delivering the power and responsiveness you need when the job demands it most.

Built for Heavy-Duty Performance

Factory intake components prioritize quiet operation over raw capability, creating airflow restrictions that rob your engine of power when you're climbing grades or accelerating onto the highway with a loaded bed. This system eliminates those limitations with T304 lightweight aluminum piping and a dedicated heat shield that pulls in massive volumes of cool, dense air—exactly what your Duramax needs to produce maximum torque and horsepower.

The result? Up to 10% more horsepower and torque, sharper throttle response across the entire power band, and improved fuel efficiency. Whether you're towing a gooseneck trailer or running empty, you'll feel the difference instantly—more pulling power, faster acceleration, and confident performance under load.

Engineered for Extreme Conditions

The integrated heat shield is the game-changer. By blocking radiant engine heat and drawing air from outside the engine bay, this system ensures your Duramax breathes the coldest, densest air possible. Cooler air means more oxygen per combustion cycle, which translates directly to increased power output and better fuel economy—critical advantages when you're putting your Silverado to work.
