Hoypeyfiy Carburetor Intake Manifold Boots for Yamaha XVS1100 1999–2009 — Left & Right Direct-Fit, OEM-Style

If your Yamaha V-Star 1100 shows signs of rough idle, uneven throttle response, or fuel-air leaks, worn intake boots could be the cause. These Hoypeyfiy aftermarket intake manifold boots are designed as direct-fit replacements for the left and right carburetor interfaces on XVS1100 models from 1999 to 2009. They mirror the OE mounting points to simplify installation and bring worn rubber parts back to factory-like condition without the OEM price tag.

How do these boots improve rideability on my V-Star 1100?

Intake manifold boots keep the carburetor and engine sealed so the air-fuel mixture remains consistent. New boots reduce vacuum leaks that cause stumbling, hard starting, or surging at idle. Installing fresh boots helps restore smooth acceleration and steadier idling by preventing unmetered air entry.

• Direct-fit for both left and right carburetors on XVS1100 models.
• Replaces part numbers 5EL-13596-00-00 and 5EL-13586-00-00.
• Improves vacuum integrity for better throttle response.
• OEM-style mounting for simplified installation.

Will these boots fit my specific V-Star 1100 model and year?

These boots are compatible with V-Star 1100 Classic and Custom models from 1999 through 2009, and select Silverado and Midnight Custom variants from 2005–2009. They are made to match the original geometry and bolt pattern so they mount in the same position as the originals. Verify OEM part numbers or compare the shape to your existing boots if you are unsure.

• Fits V-Star 1100 Classic and Custom (1999–2009).
• Compatible with Silverado and Midnight Custom (2005–2009).
• Cross-references the listed OEM part numbers for accuracy.

How easy is installation and what tools are needed?

Installation is straightforward for anyone comfortable with basic motorcycle maintenance. You’ll remove the carburetors or loosen mounts as needed, swap the old boots for the replacements, and re-tighten clamps and bolts to spec. No special tools are required beyond standard hand tools, and the boots are shaped to align with factory fasteners.

• Simple swap using common hand tools (screwdrivers, wrenches).
• No custom modification required; designed for bolt-on installation.
• Replace both left and right boots together for balanced performance.

What are these boots made of and how durable are they?

The boots are manufactured from resilient rubber compounds formulated for engine bay environments. They resist heat, vibration, and fuel vapors better than aged, cracked stock boots. While not OEM-branded, they are built as aftermarket replacements intended for long-term use when fitted correctly.

• Engine-grade rubber to withstand heat and vibration.
• Designed to resist fuel and oil exposure under normal conditions.
• Sold as a matched left and right set for consistent sealing.

Who is this for? Riders and mechanics who own a Yamaha XVS1100 V-Star Classic, Custom, Silverado, or Midnight Custom (model years listed) and want an affordable, direct-fit replacement for cracked or leaking intake boots. This set is ideal for DIY maintainers, restoration projects, or anyone troubleshooting engine vacuum leaks or inconsistent carburetor behavior.
