Show original supplier description
The HSP Diesel Deluxe No Bridge/Cold Side Bundle Kit is a comprehensive performance upgrade designed for 2013-2014 Chevrolet and GMC trucks equipped with the LML Duramax engine. The kit features a high-flowing cold air intake with an increased 4.5-inch intake tube diameter, paired with a quality filter and a heat shield box to ensure only cool engine bay air is drawn in. This intake system alone has been dyno-tested to achieve an average increase of 20 horsepower and 58 lb-ft of torque. Additionally, the bundle replaces several components prone to failure or performance restriction. It includes a 3-inch diameter, mandrel-bent hot side intercooler tube designed for a straighter connection to the intercooler, minimizing turbulence and improving flow by up to 40 percent. A similarly designed 3-inch cold side tube further enhances system flow and performance. The kit also replaces the stock upper coolant tube with a durable metal version, available in various powder coat finishes for aesthetic appeal, and provides a CNC-bent aluminum factory replacement coolant tank that resists discoloration and cracking. Specific fitment is for 2013-2014 LML Duramax engines (VIN code 8). This kit is explicitly stated to only fit these specific years due to minor engine bay changes, even if the VIN code might otherwise suggest broader compatibility.
