20723985 Pipe | Genuine Volvo Penta Part

🔧 Product Description

Rigid intake-air pipe used between the air-cleaner assembly and the turbocharger/intake system on heavy-duty TAD16 engines. It is an air-induction component, not a coolant or lubricating-oil pipe.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD721GE
• Volvo Penta TAD722GE

• Engine Family: TAD
• HP Range: Approximately 750 HP
• Year Range: Approximately 2000s-2010s

⚙️ Key Features

• OEM formed routing and connection diameters
• Maintains unrestricted filtered-air flow to the turbocharger
• Works with the original air cleaner, filter element and hose clamps
• Preserves clearance from hot and moving engine components
• Suitable for replacement of a cracked, dented or internally contaminated pipe
• Engine type: 16.1 L six-cylinder turbocharged/aftercooled industrial diesel

🔌 Function

Carries clean, filtered intake air from the air cleaner to the turbocharger or intake duct without introducing restriction or unfiltered leakage.

⚠️ Common Signs of Failure

• Cracks or loose joints allowing unfiltered air into the engine
• Whistling, hissing or intake noise under load
• Dents, collapsed sections or internal contamination restricting airflow
• Dust tracks downstream of the air-filter connection
• Reduced power, increased smoke or premature turbocharger wear

🛠️ Service Notes

• Offer the pipe up and check it reaches both connections freely before you tighten anything — a rigid pipe pulled into place is a pipe left under permanent strain, and strained pipes crack at the fittings in service
• Renew the sealing washers, O-rings or union seals that go with the pipe rather than reusing the old ones, and make sure the seats, faces and threads are clean
• Keep the ends capped while you work and blow or flush a pipe through before fitting; anything left inside goes straight into the oil, fuel or coolant system
• Tighten unions and banjo bolts evenly to the figures in the workshop manual for your engine — overtightening distorts the seat and starts the leak you were trying to cure
• Refit every clip and support bracket in its original place and keep the pipe clear of hot or moving parts so it cannot chafe or be shaken to failure
