S&B Filters Cold Air Intake 75-5136 | 2020-2023 Duramax 6.6L L5P

Maximum Performance for Your Duramax L5P
Upgrade your Silverado or Sierra 6.6L Duramax L5P with the S&B Cold Air Intake. Engineered to minimize air restriction and flow significantly better than stock, this system delivers cooler, denser air for increased power, throttle response, and engine protection. The fully enclosed airbox keeps dirt and debris out while blocking hot engine air.

New Snap-In Lid Design
Forget screws—S&B’s innovative snap-in lid makes installation and filter inspections quick and easy. A silicone edge trim ensures a tight seal to keep out power-robbing engine heat. This intake comes with a massive, highly-efficient filter available in two options:

• 8-Layer Cotton Cleanable (Washable & Reusable)
• Dry Extendable (Disposable)

Premium Silicone Components
All critical components—the filter, coupler, lid seal, and box plug—are built from premium silicone. Unlike rubber, silicone withstands up to 400°F without cracking, tearing, or deteriorating over time, ensuring long-lasting durability and performance.

Choose Your Airflow
The intake features three air inlet points for maximum airflow. Want to fine-tune your setup? An optional box plug is included to seal one inlet point, giving you flexibility to balance airflow and cooler temps. For best results, run without the box plug—except in extreme heatwave conditions.

No Check Engine Lights
Precision-engineered with a properly mapped Mass Air Flow (MAF) sensor plate, this intake runs flawlessly with both stock calibration and tuned setups. That means you’ll enjoy more performance without worrying about throwing codes.
