HSP Diesel Cold Air Intake for 2013-2016 Chevrolet and GMC LML Duramax

HSP Cold Air Intake for 2013-2016 Chevrolet / GMC Duramax LML

Part Number: 502-2-HSP

The 502-2-HSP, best known as the HSP Cold Air Intake for the 2013-2016 LML Duramax-equipped Chevrolet and GMC trucks, is a game-changer. A cold air intake is often one of the first upgrades enthusiasts make and for good reason. HSPs intake system is engineered to deliver exceptional performance and style.

Why Choose the HSP Cold Air Intake?

Factory intake systems, especially on turbocharged diesel engines, are restrictive and inefficient. Airflow is limited, and OEM filters often underperform. HSP saw the opportunity for major improvements with the LML platform and the results speak for themselves.

What Sets the HSP Intake Apart?

The HSP Cold Air Intake delivers an average increase of 20 horsepower and 58 lb-ft of torque. We accomplished this by upgrading to a 4.5" mandrel-bent aluminum tube, providing consistent, unrestricted airflow. A custom heat shield box keeps hot engine air out, allowing denser, cooler air into the system which means more power and better throttle response. CNC-machined sensor blocks ensure a perfect fit, making installation seamless and clean.

*Special Note: Designed specifically for trucks equipped with the factory VGT turbo, model years 2013-2016 only.
