Ferrea Intake Valve Set 2 36mm 5.49mm 02-06 Honda CRF450

Competition intake valve for the 02-06 Honda CRF 450 (36mm head, 5.49mm stem diameter) designed to provide reliable sealing and consistent valve motion under racing conditions.

Product overview: Manufactured by Ferrea, this set contains two competition-grade intake valves specified for Honda CRF 450 models from 2002–2006. The valves are configured with a 36mm head diameter and a 5.49mm stem diameter to match factory cylinder head dimensions for direct replacement or performance-oriented valvetrain builds.

• 36mm head diameter — Matches specified head size to ensure proper valve-seat contact and consistent airflow geometry.
• 5.49mm stem diameter — Provides the stated stem dimension for correct guide clearance and repeatable valve motion.
• Intake valve, competition specification — Designation indicates suitability for high-demand valvetrain applications where durability and dimensional accuracy matter.
• Set of 2 — Supplied quantity aligns with single-cylinder intake valve replacement or matched pair needs.
• Vehicle compatibility — Specified for 02–06 Honda CRF 450 applications to maintain fit and function with the OEM cylinder head.

Why these features matter

• Correct head diameter: Ensures the valve contacts the seat as intended, preserving combustion sealing and predictable airflow behavior.
• Specified stem diameter: Critical for proper guide fit and to minimize lateral play that can affect valve timing and wear.
• Competition specification: Indicates components are intended for higher load cycles and tighter dimensional tolerances than generic replacements, supporting consistent engine performance.
• Matched set delivery: Provides two valves with consistent dimensions to help maintain balanced intake flow and valve timing across the cylinder.
