The LBZ and LMM Duramax engines are legendary for torque, and the factory intercooler boots are legendary for failing. The hot-side boot lives directly off the turbo outlet. The cold-side boot flexes with every throttle input. Heat, oil vapor, and boost pressure soften the rubber until it balloons like a balloon and blows off at 25 psi on a freeway on-ramp. This Silicone CAC Intercooler Boot Kit replaces every rubber charge air hose on the hot side and cold side with reinforced silicone that holds boost without failing.

Key Points:

• Full kit replaces all factory rubber CAC boots and intercooler connectors
• Multi-ply reinforced silicone, oil-resistant inner liner
• Internal fabric ply prevents ballooning under sustained boost
• Direct OEM fitment, factory clamp positions, no trimming
• Handles tuned boost levels without swelling or blowing off
