Mammoth Performance Intercooler Boot and Coolant Hose Kit 02-04 GM 6.6L Duramax

Give your 02–04 Silverado or Sierra a complete charge-air and cooling system upgrade with this 3-inch polished intercooler pipe and silicone hose kit. Designed to work with the factory intercooler, this kit replaces the aging OEM intercooler plumbing and radiator hoses with heavy-duty components built for the demands of a hard-working Duramax. The polished intercooler pipes add a clean, upgraded look under the hood, while the silicone boots and radiator hoses help address common problems associated with cracked, damaged, or collapsed factory rubber. Whether you're refreshing a high-mileage truck, improving reliability, or cleaning up your engine bay, this kit combines several key upgrades into one package. The kit includes a hot-side and cold-side 3-inch intercooler pipe, four reinforced silicone boots, eight stainless T-bolt clamps, and upper and lower radiator hoses. The high-temperature silicone construction is rated to 350°F and designed to maintain a reliable seal through the heat, pressure, and vibration of a 6.6L Duramax, while the intercooler pipes provide a durable connection between the turbocharger, intercooler, and intake system.
