🔌 Function

Carries pressurised air from the charge-air pipework into the inlet manifold, holding a sealed boost path while flexing to take up engine movement between the two rigid ends.

⚠️ Common Signs of Failure

• Whistling or huffing under load as boost escapes
• Loss of power and dark smoke when the engine is pushed
• Oily film or a dust streak tracking away from a clamp
• Rubber gone soft, swollen or split at the bead on strip-down
• Bore ballooning or collapsing when boost is applied

🛠️ Service Notes

• Check the pipe beads and clamp bands for corrosion before fitting - a pitted bead will not seal even a new hose
• A leak here reads on the gauge like a turbocharger fault, so pressure-test the charge-air side before condemning the turbo
