AFE Stage 2 Cold Air Intake Type Cx 01-04 GM 6.6L Duramax LB7

Increase the efficiency and power of your LB7 Duramax by upgrading with this cold air intake from AFE. This Stage 2 cold air intake system produces 12 HP and 28 lbs. x ft. of torque and outflows the factory intake by 42%. Enclosed in a durable 18 gauge, powder-coated heat shield; this air intake system features a massive 6" base x 7" height filter with a 4" flange washable/reusable conical air filter that improves airflow for increased horsepower and torque. This intake system also features a heat-insulating molded plastic tube that replaces the stock intake tract with a built in mass air flow sensor pad that directs increased air flow with improved volumetric efficiency for maximum performance. One-piece heat shield requires little or no assembly and the filter is constructed with 100% polyurethane for long life and multiple cleaning cycles.

This intake utilizes a huge, 5-1/2" conical Pro 5R performance air filter for maximum flow. This 5-layer progressive, oiled cotton gauze air filter provides maximum flow for increased horsepower and torque.

The air filter is housed in a one-piece, black powdercoated 18-gauge heat shield. This one-piece heat shield uses factory mounting locations for a hassle free installation.

The intake tube is designed to maximize air velocity and is dyno tested and flowed using the latest engineering tools for maximum performance, mileage and throttle response.
