S&B Cold Air Intake 75-5101

Cold Air Intake for Duramax LB7/LLY 6.6L (2001–2005)

The S&B Cold Air Intake 75-5101 fits 2001–2005 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax LB7 and LLY engines. This system replaces the factory airbox with a sealed intake design and includes a cotton cleanable filter, giving you a reusable setup built around factory fitment.

Sealed Airbox Design

This intake uses a sealed airbox that isolates the filter from engine bay heat. As a result, it supports consistent airflow into the intake system. In addition, the enclosed design helps control how air enters the system compared to the factory setup.

Cotton Cleanable Filter

The included cotton cleanable filter can be washed, re-oiled, and reused. Because of this, you don’t have to replace disposable filters over time. In addition, the layered cotton media is designed to capture contaminants while supporting airflow.

Intake Tube & Components

S&B builds this intake with a molded intake tube designed to match factory connections. As a result, it maintains proper alignment with existing components. In addition, the kit includes couplers and clamps to secure all connections.

Clear Lid & Service Access

The airbox features a clear lid for quick filter inspection. Because of this, you can check filter condition without disassembly. In addition, the lid allows easier access during routine maintenance.

Direct Replacement Installation

This intake installs using factory mounting locations. Therefore, no cutting or drilling is required. In addition, it is designed to work with factory sensors and connections.

Designed for Daily Driving & Work Use

You can run this intake on trucks used for daily driving, towing, or work applications. Because of this, it supports consistent operation without relying on the factory airbox.

Why Replace the Factory Intake

Factory intake systems use disposable paper filters that require regular replacement. As a result, long-term maintenance becomes a factor. Switching to a reusable filter setup simplifies upkeep over time.

Additional Fitment Notes

This intake fits 2001–2005 Duramax LB7 and LLY trucks. However, always confirm your vehicle’s configuration before installation.
