This is a durable air intake hose designed to connect the air filter housing to the turbocharger or intake manifold on Volvo D11, D13 engines used in FH, FM, and FMX trucks. It ensures a sealed pathway for clean air to enter the engine, vital for maintaining optimal combustion and performance. A cracked or leaking hose can lead to reduced engine power, increased soot formation, and potential turbocharger damage.
Always verify with serial number before ordering.

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
A leaking air intake hose will initially cause a noticeable loss of engine power, especially under load, and may be accompanied by a whistling or hissing sound from the engine bay. If left unaddressed, the engine may run rough, produce excessive black smoke, and the turbocharger could be starved of adequate airflow, leading to reduced efficiency and potential over-speeding.
Ensure all mating surfaces and clamps are clean and free of oil or debris before installing the new hose. Do not overtighten the hose clamps, as this can damage the hose or the connection port.
Inspect the air filter housing and the turbocharger intake port for any signs of damage or contamination when replacing the air intake hose.
