S&B Cold Air Intake 75-5091D

75-5091D Cold Air Intake for Duramax LMM 6.6L (2007–2010)

The S&B Cold Air Intake 75-5091D fits 2007–2010 Chevy Silverado and GMC Sierra 2500HD/3500HD trucks equipped with the 6.6L Duramax LMM engine. This intake system replaces the factory airbox with a sealed design & includes a dry extendable filter. Because of this, it provides a reusable intake solution designed around factory fitment.

Sealed Airbox Design

The 75-5091D cold air intake uses a sealed airbox that isolates the filter from engine bay heat. As a result, the system supports consistent airflow into the intake system. In addition, the enclosed design helps maintain controlled air delivery.

Dry Extendable Filter

This intake includes an S&B dry extendable filter. Because of this, the filter does not require oil during maintenance. In addition, you can clean & reuse the filter, which supports long-term serviceability. The extendable design also increases available filter surface area when needed.

Intake Tube & Components

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

Clear Lid & Service Access

This intake system includes a clear lid on the airbox. Because of this, you can inspect the filter without removing components. In addition, the lid allows quick access when servicing the filter.

Direct Replacement Installation

The 75-5091D cold air intake installs using factory mounting locations. Therefore, you do not need to cut or drill during installation. In addition, the system is designed to work with factory sensors and connections.

Designed for Daily Driving & Work Use

You can run this intake system 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. By installing the 75-5091D intake, you switch to a reusable filter and a complete intake system.

Additional Fitment Notes

This intake fits 2007–2010 Chevy and GMC 2500HD/3500HD trucks with the 6.6L Duramax LMM engine. However, always confirm your vehicle’s configuration before installation.
