HD Intercooler And Coolant Hose Kit 11-16 GM 6.6L Duramax LML

Give your truck a complete upgrade to its cooling and charge-air systems with the Mammoth Performance Heavy Duty Silicone Intercooler & Coolant Hose Kit. Instead of waiting for aging factory rubber to crack, swell, or fail, this complete kit replaces both the intercooler boots and the coolant hoses in a single installation. Years of heat cycles, turbo boost, coolant exposure, and engine vibration can take their toll on factory components, leading to boost leaks, lost performance, coolant leaks, and overheating. Whether your LML is a daily driver, heavy-duty tow rig, or tuned performance truck, this kit provides a durable upgrade built to withstand the demands of a hard-working Duramax. Built from multi-ply silicone reinforced with high-strength fabric layers, the hoses and boots are designed to handle the heat, boost pressure, and vibration of the LML while resisting the cracking, swelling, and deterioration common with factory rubber. The intercooler boots help maintain a reliable boost seal, while the coolant hoses provide durable protection against the cooling system's temperatures and pressures. Direct OEM-style fitment follows factory routing and connections for a straightforward installation without modifications, and stainless steel clamps provide secure, reliable seals throughout.
