Suzuki ATV owners, if you're dealing with air leaks or rough running on your Quadrunner or Kingquad, this MOTO1988 intake manifold boot might be exactly what you need. This is a direct replacement for OEM part number 13101-19B50 and fits a bunch of Suzuki models including the Quadrunner 250 (1988-2002 across various model years and versions), Kingquad 250 (1996-1998), and Kingquad 300 (1991-2002). The boot connects your carburetor to the engine intake, and when these get old, they can crack or become brittle, causing air leaks that mess with your fuel mixture. Installation is pretty straightforward if you're comfortable with basic carb work - just remove the old boot and swap in this new one. The quality seems solid, and it fits perfectly without any modification needed. I used this on my 1995 Quadrunner 250 that was having idle issues, and it solved the problem completely. The rubber feels durable and should hold up well to engine heat and vibration. Before ordering, definitely double-check your specific model and year against the compatibility list, as Suzuki made several variations of these ATVs. If you're experiencing poor performance, hard starting, or irregular idle, this affordable replacement part could get your ATV running smoothly again without the cost of dealership parts.
