Honda TRX450R / TRX450ER Carburetor Intake Boot Flange – 2006‑2012 – Replaces 16210‑MEB‑670

OVERVIEW

This carburetor intake boot flange maintains a secure, airtight seal between the airbox and carburetor, ensuring consistent airflow and stable engine operation. Constructed from heavy-duty molded rubber, it serves as a direct-fit replacement component that prevents vacuum leaks caused by aging factory seals. Designed exclusively for sport ATV platforms like the Honda TRX450 series, it restores critical intake integrity without requiring custom adapters or fabrication.

ENGINEERING & PERFORMANCE

The reinforced rubber compound resists heat degradation and chemical breakdown, maintaining pliability under exhaust temperatures and prolonged vibration. Engineered to duplicate the exact internal diameter and mounting profile of the original equipment part, this flange delivers reliable carburetor sealing and steady fuel-air mixture delivery. Its precision mold geometry guarantees a snug bolt-on installation that eliminates gaps around the intake tract, preventing unmetered air ingress and preserving crisp throttle response across the entire RPM band.
