Key Features

• Standard replacement intake valve for engine valve train service
• High alloy steel valve material for strength and heat resistance
• Coated finish for added surface protection
• 45-degree seat angle for proper valve seating
• 1.418 in. valve head diameter and 0.234 in. stem diameter
• Part number V5806 for catalog and service matching

Detailed Description

Melling V5806 intake valves are engineered with precision manufacturing and superior-grade alloy materials to meet demanding engine specifications. The steel construction, coated finish, and high alloy steel valve material support durable operation under heat and fatigue stress. This intake valve is a direct service part for Subaru Legacy, Subaru Outback, Subaru Forester, Subaru Impreza, Subaru Baja, and Saab 9-2X applications where the original valve dimensions and seat geometry must be maintained. The V5806 is identified by a 121.0 mm overall length, 36.0 mm valve head diameter, and single lock groove design.

What It Is Used For

• Restoring intake valve sealing in a worn cylinder head
• Addressing compression loss caused by valve wear or damage
• Replacing a valve with heat-related surface deterioration
• Correcting poor engine performance linked to valve-train wear
• Servicing engines that require standard replacement valve dimensions

Installation Notes and Tips

Verify valve head diameter, stem diameter, seat angle, and overall length before installation. Match the replacement valve to the cylinder head specification and inspect related valve-train components for wear before assembly. This part cross-references DNJ (e.g., IV710, IV720) for the same application. Use the part number V5806 when confirming catalog fitment for Subaru and Saab engine service.

Quality Assurance

Melling states that its intake valves are produced with precision engineering, controlled material selection, and advanced manufacturing processes to meet exacting performance requirements. The V5806 is a standard replacement valve designed to deliver dependable service in demanding engine environments.
