Description
Overview:
The Inlet Pipe is a genuine Husqvarna component designed for the intake side of professional chainsaws. Built from a durable, fuel- and oil-resistant elastomer, it provides a secure, airtight path for the air-fuel mixture between the carburettor and the engine. A sound inlet pipe is essential for stable idle, clean acceleration, and protecting the cylinder from damaging air leaks. This OEM part (Husqvarna MPN 521 99 25-03) is engineered for a precise fit on the 365 X-Torq and 372XP X-Torq, supporting efficient running under daily site or forestry use. Its robust construction helps resist cracking and hardening caused by vibration, heat, and exposure to modern fuels, making it a reliable replacement choice during routine servicing or when diagnosing poor running, erratic idle, or lean conditions.
