The Honda 17251-ZJ1-851 Air Cleaner Connecting Tube is a genuine OEM component designed for GX610, GX620, and GX670 horizontal shaft engines. As a direct Honda OEM replacement, this tube is manufactured to the exact dimensions required for a proper seal between the air cleaner and the intake, ensuring unobstructed airflow into the engine. Verify your engine's serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks across these engine families.
Key Features
- Genuine Honda OEM — sourced directly from Honda, this Air Cleaner Connecting Tube meets the same dimensional and material specifications as the part that left the factory, ensuring an airtight connection in the air intake path.
- Exact Intake Fit — engineered to match the OEM routing and connection points on GX610, GX620, and GX670 engines, eliminating the air leaks and fitment gaps that a worn or cracked tube can cause.
- Correct Airflow Delivery — a compromised connecting tube allows unfiltered air to bypass the cleaner element, accelerating internal engine wear; this replacement restores the intake seal and protects the engine.
- Serial Number Verification Recommended — Honda updates part supersessions across serial ranges on the GX610, GX620, and GX670; confirm your engine's serial number against the fitment table to ensure this is the correct tube for your unit.
The Air Cleaner Connecting Tube channels filtered air from the air cleaner assembly into the engine's intake, forming a sealed passage that keeps dirt and debris out of the combustion chamber. On large-displacement horizontal shaft engines like the GX610, GX620, and GX670, maintaining a clean and airtight air supply is critical to consistent power output and long engine life. When this tube cracks, collapses, or loses its seal, unfiltered air enters the intake — leading to accelerated cylinder and ring wear and a gradual loss of engine performance.
