Intake manifold adapter for Yamaha WR450F and YZ450F, original part number: 5XD-13597, carburetor interface pipe and intake manifold gasket.

【Precise Fit】This product is an original intake manifold (also known as a carburetor hose or intake pipe) specifically designed for the high-performance four-stroke off-road/racing motorcycles Yamaha WR450F and YZ450F. It exactly matches the original part number 5XD-13597, ensuring a perfect match in dimensions, shape, and material properties.

【Main Functions】As the only flexible connection between the carburetor (or throttle body) and cylinder head, it provides a complete seal, preventing the fuel-air mixture from leaking into the combustion chamber. In high-compression, high-performance 450cc single-cylinder engines, the tightness of this component directly affects: starting reliability, especially in cold weather or at high altitudes; idle stability (preventing fluctuations and stalling due to air leaks); The throttle response and performance (ensures a consistent air supply, thus optimizing engine potential). and fuel efficiency (prevents unmetered air intake and disruption of the preset air-fuel ratio). [Materials and Durability] Manufactured from high-performance rubber or elastomer of the same quality as genuine Yamaha parts, this component offers excellent resistance to heat (even at the high temperatures found in the engine compartment), oil (and fuel vapors), and tear strength. Optimized to absorb strong engine vibrations and frame flex in off-road conditions, it ensures long-term reliability even under the harshest circumstances.
