The 2.8L Duramax in the Colorado and Canyon is a small diesel that works hard -- and the factory intercooler couplings are rubber that gives up early. Heat from the turbo, oil vapor from the PCV system, and sustained boost pressure swell the OEM rubber couplings until they crack at the clamps or blow off under load. This Intercooler Couplings Tube Kit replaces the factory rubber connectors with reinforced silicone that holds boost from the turbo to the intercooler and back.

Key Points:

• Kit replaces factory rubber intercooler couplings and 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
• Maintains boost seal on stock and tuned 2.8L Duramax engines
