It stays flexible in freezing winters and won't melt or deform during summer towing.Reinforced Construction: Features internal spiral wire reinforcement and multi-ply fabric layers to prevent collapse under high vacuum or expansion under high boost, maintaining consistent airflow.Direct OEM Replacement: Molded to the exact curvature and length of the original GM #904-130 hose. Fits stock locations perfectly without rubbing against fans, belts, or chassis components.Complete Installation: Comes with new, heavy-duty clamps. Reusing old clamps is a leading cause of repeat leaks; our kit ensures you have fresh hardware for a secure grip.📋 Vehicle Compatibility:Chevrolet:2008-2010 Silverado 2500HD / 3500HD (6.6L Duramax LMM)2011-2016 Silverado 2500HD / 3500HD (6.6L Duramax LML)GMC:2008-2010 Sierra 2500HD / 3500HD (6.6L Duramax LMM)2011-2016 Sierra 2500HD / 3500HD (6.6L Duramax LML)Replaces Part Numbers: 904-130, 904-130A, 25773396, 22832993.🔧 Symptoms of a Failing Boot:Loss of power during acceleration or towing.Excessive black smoke from the exhaust.Whistling or hissing noise from the engine bay.Poor fuel economy.Visible cracks, oil saturation, or swelling on the existing hose.🛠️ Installation Tips:Cool Down: Ensure the engine and turbo system are completely cool before starting.Inspect: Check the metal piping ends for burrs or sharp edges that could damage the new boot. Clean thoroughly to remove old oil and debris.Lubricate: Use a mild soapy water solution or silicone spray on the pipe ends to slide the new boot on easily. Do not use petroleum-based grease as it can degrade EPDM rubber over time.Clamp: Position the included clamps over the bead marks on the boot and tighten to the specified torque.Test: Start the engine and check for leaks while gently revving.⚠️ Important Note:This kit is designed for Stock or Mildly Modified applications. For trucks with extreme aftermarket tuning (>500HP) or significantly increased boost levels, a specialized heavy-duty silicone upgrade might be considered, though this OE-replacement offers superior durability for standard operating conditions.Package Contents:1 x Intercooler Boot (Turbo to Intercooler)2 x Heavy-Duty Stainless Steel Clamps

Directly replaces GM Part #904-130 (also fits 904-130A). Note: Please verify your engine code and model year before ordering to ensure compatibility.
• 【🔥 PREMIUM HEAT-RESISTANT EPDM】 Constructed from advanced EPDM (Ethylene Propylene Diene Monomer) rubber reinforced with multiple plies of high-tensile fabric. Unlike cheap silicone or generic rubber, this material resists cracking, hardening, and swelling under extreme turbo heat (up to 400°F+) and high boost pressure, ensuring a long service life in harsh under-hood environments.
• 【💨 RESTORE BOOST & ELIMINATE LEAKS】 Designed to seal perfectly between the turbocharger outlet and the intercooler inlet. Fixes common issues like boost leaks, whistling noises, black smoke, and loss of power. Restores factory airflow efficiency, improving throttle response and fuel economy by preventing pressurized air from escaping.
• 【🔧 COMPLETE KIT WITH HEAVY-DUTY CLAMPS】 Includes the pre-formed intercooler boot plus high-grade stainless steel T-bolt or constant-tension clamps (as per OEM spec). No need to reuse old, stretched clamps or make extra trips to the auto parts store. Everything needed for a secure, leak-free installation is in one box.
• 【🛡️ OE-LEVEL QUALITY & TESTING】 Manufactured to meet or exceed Original Equipment (OE) standards for dimensional accuracy and durability. Each batch undergoes rigorous testing for burst pressure and heat cycling. Backed by a professional-grade warranty, giving you confidence in your repair whether you are towing heavy loads or daily driving.
