21412904 Inlet Manifold | Genuine Volvo Penta Part

🔧 Product Description

Cast intake manifold for the Volvo Penta TWD1643GE generating-set engine. It distributes charge air from the connecting pipe and charge-air cooler evenly to the cylinder-head intake ports while providing the correct mounting points for sensors, gaskets and associated air-system hardware.

🚤 Compatibility

• Engine Family: D, TWD

⚙️ Key Features

• Genuine Volvo Penta TWD1643GE inlet manifold
• Cast manifold matched to the 16-litre engine air system
• Distributes charge air evenly across all cylinders
• Correct sensor, flange and gasket interfaces
• Direct replacement for a cracked or damaged original manifold
• Engine type: Volvo Penta 16-litre inline six-cylinder industrial diesel

🔌 Function

Receives compressed and cooled intake air and divides it evenly among the engine cylinders.

⚠️ Common Signs of Failure

• Boost leakage at the manifold or gaskets
• Cracks or porosity in the casting
• Oil mist or soot tracking around flange joints
• Uneven cylinder performance caused by air leakage
• Damaged sensor ports or mounting threads

🛠️ Service Notes

• Blank the open ports as soon as the manifold is off, so nothing can drop into a cylinder or the head while it is away
• Clean both mating faces without scoring them, check the manifold for flatness, cracks and corrosion, and fit new gaskets and seals throughout
• Clean out oil, soot and carbon deposits from the manifold interior before refitting, and look at the crankcase breather arrangement if the build-up is heavy — refitting a fouled manifold puts the restriction straight back
• Tighten the fasteners evenly, working outwards from the centre in stages to the figures given in the workshop manual for your engine
• Refit and check all charge air, breather and sensor connections and their clips; an air leak on a pressure-charged inlet shows up as lost power and smoke rather than an audible leak
