Product Overview
Restore the legendary torque and smooth power delivery of your Yamaha "Eleven" with the GOOFIT High-Performance Intake Manifold Boot. Specifically engineered for the Yamaha XS1100 and XJ1100 series, this precision-molded interface is a direct replacement for OEM #2H7-13586-00.
On high-displacement vintage motorcycles, the intake manifolds are the primary defense against vacuum leaks. Over years of service, heat and fuel vapor cause the original rubber to harden and crack. This results in "unmetered air" entering the cylinders, leading to erratic idling, backfiring on deceleration, and a loss of that signature inline-four smoothness. Our boots are made from high-grade, durable rubber designed to perfectly seal the gap between your carburetors and the engine.
Product Compatibility
Direct replacement for the Yamaha XS1100 4-cylinder series. Please verify your model's OEM code.

Key Features
- Perfect Vacuum Seal: Ensures an airtight connection between the carburetor and the engine. This is critical for evenly distributing the fuel-air mixture to each of the four cylinders, providing "new power" and a steady, reliable idle.
- Premium Rubber Material: Constructed from high-quality, high-density rubber that maintains flexibility even under extreme engine heat. It effectively resists the cracking and "dry-rot" common in 40-year-old vintage components.
- Optimized Engine Performance: By fixing vacuum leaks, these manifolds eliminate common issues like "hanging idles" or hesitation during acceleration, allowing your engine to operate at peak efficiency.
- Direct "Plug-and-Play" Fit: Precision manufactured to meet 2H7 factory dimensions. Designed for a direct bolt-on installation, making it easy for both DIY enthusiasts and professional restorers to replace worn-out joints.
- Rugged Durability: Built to withstand the intense thermal environment of an 1100cc air-cooled engine, ensuring a long service life and consistent performance through years of touring.
