Overview

The HSP Cold Air Intake is designed for 2013-2016 LML Duramax-equipped Chevrolet and GMC trucks. Factory intake systems can be restrictive, limiting airflow and filter performance. This intake system upgrades to a 4.5" mandrel-bent aluminum tube for consistent, unrestricted airflow.
Show original supplier description
The HSP Cold Air Intake for the 2013-2016 LML Duramax Chevrolet and GMC trucks is engineered to significantly improve upon restrictive factory intake systems. This system features a 4.5" mandrel-bent aluminum tube, designed to provide consistent and unrestricted airflow. A custom heat shield box is included to isolate the filter from hot engine bay air, promoting the intake of denser, cooler air. This results in increased horsepower and torque, as well as improved throttle response. Key specifications include an average increase of 20 horsepower and 58 lb-ft of torque. The intake tube is constructed from aluminum and has a diameter of 4.5 inches. The system is designed to fit trucks equipped with the factory VGT turbo, specifically for model years 2013-2016 (VIN Code 8). The package includes the 4.5" Cold Air Intake Tube, Heatshield Box, Heatshield Box Lid, a 4.5" Filter, various clamps and boots, aluminum rivets, button head screws, trim lock, and a heatshield box lid backer plate.
