Cold Air Intake for 2001-2004 Silverado / Sierra Duramax 6.6L

Description

The factory airbox on your 2001-2004 GM Silverado / Sierra chokes airflow. This S&B cold air intake replaces it with a fully enclosed, one-piece airbox and an oversized high-flow filter engineered to feed your 6.6L Duramax clean, cool air — without tripping a check engine light.

Every S&B intake is tested to the ISO 5011 standard and tuned to hold correct MAF and fuel-trim values, so it runs clean stock or lightly tuned.

• Fully enclosed one-piece airbox seals the filter from hot engine-bay air
• Clear lid for at-a-glance filter checks while locking out heat
• Choose 8-layer cotton cleanable (oiled) or dry extendable media
• Heat-resistant silicone couplers and seals
• Bolt-in install with basic hand tools, no cutting
• Backed by S&B’s Million Mile Warranty — won’t void your factory warranty
