21087694 Charge Air Pipe | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Charge Air Pipe - Part Number: 21087694

A genuine Volvo Penta charge-air pipe forming the companion section of the early TAD732GE/TAD733GE intercooler ducting. The pipe is shaped to connect the specified hose and sealing interfaces without loading the intercooler or intake connection. Correct pipe selection is important because later serial ranges use revised charge-air pipes, supports and cooling-package components.

⚙️ Key Features

• Companion rigid boost pipe in the early D7 generator cooling package

• Engine-specific bends maintain clearance and alignment

• Smooth internal bore reduces boost-pressure loss

• Correct sealing-end geometry for the original O-ring, hose and clamp system

• Serial-controlled and not interchangeable with later revised charge-air pipes
