4-piece set: YAMAHA YZF600R intake manifold connection hose for carburetor, original part number 4JH-13586 4JH-13596, intake manifold gasket

【Perfect Fit】This product is a set of four genuine intake manifolds, specifically designed for the YAMAHA YZF600R four-cylinder sport motorcycle (carbureted version). The set exactly matches the original part numbers 4JH-13586 and 4JH-13596. Please check the exact part number of the part you are replacing before purchasing to ensure full compatibility. 【Important Function】The four intake manifolds in this set are essential sealing elements that connect the carburetor to the engine's four cylinder heads. Their primary function is to ensure a perfect seal and even distribution of the air-fuel mixture to each cylinder. This is crucial for stable idling, balanced power delivery, linear throttle response, and optimal combustion in multi-cylinder engines. 【Solves Common Problems】Rubber parts age over time and with use. Replacing all four intake manifolds simultaneously permanently eliminates intake leaks caused by hardened, cracked, or deformed hoses, thus improving performance: starting problems or rough idling, poor acceleration, sluggish throttle response, engine vibrations due to uneven cylinder running, misfires, or power loss due to a lean fuel-air mixture. [Materials and Quality] Made from high-quality, oil- and high-temperature-resistant rubber, the manifolds offer excellent elasticity and high resistance to aging, ensuring optimal sealing even under high temperatures and strong vibrations. [Installation and Verification Notes] Verification: Ensure your YZF600R has a carburetor and check the replacement part number (4JH-13586 or 4JH-13596). Professional Installation: It is recommended that this work be performed by a qualified technician. During assembly, disassemble the parts one after the other, clean all contact surfaces (carburetor outlet and engine intake) and tighten them evenly in a crisscross pattern using suitable hose clamps to ensure constant pressure at all connection points and to avoid leaks.
