Detailed Product Information

IV107 is an engine intake valve engineered for vehicles that require a 34 mm head, 6.5 mm stem, and 109.5 mm overall length. The nitride-coated finish helps reduce friction and improve surface durability under repeated heat and mechanical loading. This makes the valve a practical choice for intake valve service on engines used in the Hyundai Sonata, Kia Optima, Mitsubishi Eclipse, Mitsubishi Lancer, and related platforms.

This part cross-references 021-3400 and V-2652 for the same application.

Common Repair Uses

• Replacing a worn or damaged intake valve during cylinder head repair
• Restoring intake sealing after valve face or stem wear
• Addressing compression loss related to valve leakage
• Repairing valvetrain damage from heat, carbon buildup, or mechanical wear
• Servicing engines that require a direct-fit intake valve with the listed dimensions

Installation Notes and Quality Assurance

Verify valve head diameter, stem diameter, overall length, and lock groove count against the original part before installation. Cylinder head inspection, valve seat condition, and stem-to-guide clearance should be checked during service to confirm proper sealing and operation. IV107 is manufactured to meet or exceed OEM quality standards and uses heat-resistant alloy construction with a nitride-coated finish for durability in demanding engine environments.
