Honda TRX500 Foreman 500 Carburetor Carb Intake Manifold Flange Boot – 2005‑2011 – Bronco

OVERVIEW

This Bronco intake manifold flange restores precise air-fuel metering for your carbureted Honda ATV. Designed as a direct OEM swap for the stock carburetor flange boot, it is precision-milled from 1051/1052 aluminum to endure extreme heat and chassis flex. Manufacturered for secure bolt-on fitment across select Honda TRX500 Foreman ATVs.

ENGINEERING & PERFORMANCE

Mounted directly behind the carburetor, this flange maintains airtight sealing between the carburetor base and the engine intake, preventing the vacuum loss that causes lean spots and hesitation. The solid 1051/1052 aluminum construction resists warping and micro-cracking caused by persistent thermal cycling and heavy engine vibration. Engineered to OEM mounting patterns and port geometry, it reinstates consistent idle speed and throttle transition without needing aftermarket spacers or adhesives.

WHY RIDERS CHOOSE THIS

Riders upgrade to this aluminum flange primarily to eliminate the recurring vacuum leaks that develop when stock composite factory parts crack under trail heat and frame flex. The rigid metal body holds its shape under compression, keeping the carburetor throat sealed so fuel mixes consistently regardless of terrain severity. By restoring exact port alignment and vibration resistance, it brings back predictable cold starts, stabilizes idle speed, and removes the need for constant choke adjustments. This targeted hardware fix addresses the root cause of lean-running Foreman engines, making routine maintenance straightforward and long-term reliability predictable.
