It’s time to ditch the restrictive plastic baffles and let your turbo actually breathe.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003ePerformance Cold Air Intake Kit with Heat Shield for Chevrolet Silverado \u0026amp; GMC Sierra 2500HD\/3500HD (L5P Duramax)\u003c\/h2\u003e\n\u003cp\u003eIf you are driving a 2017-2019 GM Heavy Duty truck, you are running the L5P 6.6L Duramax—arguably one of the most capable platforms GM has ever built. However, to meet strict NVH (Noise, Vibration, and Harshness) standards, the factory intake system is designed to be quiet, not efficient. It chokes down the air volume to muffle the induction noise, which ultimately limits throttle response and keeps EGTs higher than they need to be during heavy towing or hard acceleration.\u003c\/p\u003e\n\u003cp\u003eThis intake upgrade solves that problem by replacing the corrugated factory tubing and enclosed box with a high-flow, mandrel-bent T-306 aluminum pipe and an open-element filter system. By smoothing out the airflow path, you reduce the vacuum the turbo has to fight against. The result? A claimed 8-10% increase in horsepower and a sharper throttle response that gets that heavy truck moving faster off the line. Plus, you finally get to hear the turbo spool up—a sound the stock airbox completely hides.\u003c\/p\u003e\n\u003cp\u003eThe kit includes a durable steel heat shield powder-coated to resist corrosion and keep engine bay heat away from the intake charge. This ensures your engine is pulling in cooler, denser air rather than hot stagnant air from around the exhaust manifold. Finished in a \"Black Wrinkle\" coating, the piping matches the OEM engine bay aesthetic for a clean, professional look that doesn't scream \"cheap aftermarket part.\"\u003c\/p\u003e\n\u003ch2\u003eWhy You Need This Upgrade\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProven Power Gains:\u003c\/strong\u003e Engineered to deliver an estimated 8-10% increase in horsepower and 6-8% boost in torque by maximizing air volume.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eL5P Specific Design:\u003c\/strong\u003e Tailored specifically for the 2017-2019 6.6L Duramax architecture to ensure proper mass air flow sensor readings.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThermal Management:\u003c\/strong\u003e Includes a powder-coated steel heat shield to block engine heat and lower Intake Air Temperatures (IATs).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDurable Construction:\u003c\/strong\u003e The T-306 aluminum piping is scratch-resistant and lightweight, replacing heavy and brittle factory plastics.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWashable High-Flow Filter:\u003c\/strong\u003e Reusable design means you stop buying paper filters; simply wash and re-oil for consistent performance.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid rgb(224, 224, 224); margin-bottom: 20px; height: 78.3592px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"background-color: rgb(249, 249, 249); height: 19.5898px;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); font-weight: bold; height: 19.5898px;\"\u003eFitment\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); height: 19.5898px;\"\u003e2017-2019 Chevy\/GMC 2500HD\/3500HD\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); font-weight: bold; height: 19.5898px;\"\u003eEngine Code\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); height: 19.5898px;\"\u003e6.6L Duramax L5P (Diesel)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: rgb(249, 249, 249); height: 19.5898px;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); font-weight: bold; height: 19.5898px;\"\u003eInstallation\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); height: 19.5898px;\"\u003eBolt-On \/ Simple Hand Tools\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 19.5898px;\"\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); font-weight: bold; height: 19.5898px;\"\u003eMaterial\u003c\/td\u003e\n\u003ctd style=\"padding: 10px; border: 1px solid rgb(224, 224, 224); height: 19.5898px;\"\u003eT-306 Aluminum \/ Black Wrinkle Finish\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThis system is designed as a direct replacement for the OEM assembly.
