Mammoth Performance Silicone Intercooler Boot Kit 04.5-05 GM 6.6L Duramax LLY

Description

Keep your Silverado or Sierra's charge-air system sealed and ready for the demands of daily driving or towing with this heavy-duty silicone intercooler boot kit. Factory rubber boots can weaken over time from repeated heat cycles and boost pressure, increasing the risk of leaks or a boot blowing off under load. These upgraded silicone boots provide a stronger, more durable connection designed to handle the elevated boost pressures of a modified or hard-working Duramax. Built from high-quality silicone, these boots are designed to withstand over 100 PSI of boost while providing excellent resistance to heat and the harsh conditions found in a diesel engine bay. The kit includes three heavy-duty silicone intercooler boots and six constant-tension T-bolt clamps for a secure installation and consistent clamping force.
