PPE Front EGR Cooler Feed Hose 11-16 GM 6.6L Duramax LML

Are you dealing with a worn or cracking OEM hose? The PPE Horizontal EGR Cooler Coolant Feed Hose is one of those small upgrades that plays a big role in keeping your Duramax reliable. Designed to replace the factory feed hose to the EGR cooler, this component addresses a common weak point in the cooling system: aging rubber hoses that can crack, leak, or fail under heat and pressure. If you’re maintaining your truck or fixing a coolant issue, this is a simple upgrade that helps restore proper coolant flow and prevent future failures. It’s a smart move for anyone looking to avoid downtime, protect engine components, and keep their Duramax running strong, whether it’s a daily driver or work truck.

Built from heat-resistant silicone, this hose is engineered to outlast the factory rubber equivalent. Unlike OEM hoses that degrade over time, silicone construction resists cracking, hardening, and swelling caused by constant exposure to high temperatures and coolant. This upgraded material maintains flexibility while handling pressure fluctuations within the cooling system, ensuring long-term durability and consistent performance. Designed as a direct-fit replacement, it installs easily while delivering a more robust solution.
