⚙️ Key Features

• Air duct for the air-cleaner-to-turbocharger intake run
• 0.4 kg
• 5 applications across TAD-series engines
• Holds the original internal diameter, routing and connection geometry

🔌 Function

Carries filtered air from the air cleaner to the turbocharger inlet, keeping the bore and routing so the compressor draws clean air without restriction.

⚠️ Common Signs of Failure

• A whistle or roar from the intake that rises with load
• Power down and black smoke as the turbo is starved of air
• A dust track visible downstream of a split - unfiltered air is reaching the engine
• Duct found cracked at a bend or collapsed inwards
• Clamp seats distorted or the sealing lip torn

🛠️ Service Notes

• Any unfiltered air path is dust straight into the engine - renew a split duct rather than taping it
• Check the clamps and the air-cleaner outlet seal at the same time
• Inspect the compressor wheel for dust damage if a split has been open for any length of time
