Engine Intake Valve Overview

This DNJ engine intake valve, part number IV120, is a direct-fit replacement built for precise air-fuel flow into the combustion chamber. It is engineered for applications across Hyundai and Kia models, with nitride-coated construction for added wear resistance and corrosion protection.

Key Features

• Nitride-coated surface for improved friction control and durability
• Premium-grade intake valve construction for valvetrain service
• 32.1 mm valve head diameter and 6 mm stem diameter
• 114.4 mm overall length with one lock groove
• Direct-fit design for application-specific engine repair

Detailed Description

Part number IV120 is an engine intake valve designed to restore proper intake flow in compatible Hyundai Elantra, Hyundai Tucson, Kia Sportage, Kia Spectra, Kia Spectra5, Kia Soul, and Hyundai Tiburon applications. As an intake valve, it opens at the correct camshaft interval to admit the air-fuel charge needed for combustion. The nitride-coated finish helps the valve handle heat, reduce friction, and resist wear in demanding engine conditions. DNJ manufactures this valve to meet or exceed OEM quality standards, making it a practical choice for valvetrain service where accurate dimensions and stable operation matter.

Common Repair Uses

• Restores intake sealing when a worn valve affects compression
• Addresses rough running caused by valve wear or heat damage
• Helps correct loss of power from poor cylinder breathing
• Supports engine rebuilds requiring a direct-fit intake valve
• Replaces a damaged valve in high-heat valvetrain service

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and lock groove count before installation. This part fits 2001-2012 Hyundai Elantra, 2010-2011 Kia Soul, 2005-2010 Kia Sportage, 2005-2009 Hyundai Tucson, 2004-2009 Kia Spectra, 2005-2009 Kia Spectra5, and 2003-2008 Hyundai Tiburon, intake applications. Professional cylinder head service is recommended to confirm seat condition, guide wear, and valve clearance during assembly. Part number IV120 should be matched to the engine specification listed for the vehicle.

Quality Assurance

DNJ Engine Intake Valves are manufactured to meet or exceed OEM quality standards and use heat-resistant materials with a nitride-coated finish for durability in high-temperature engine environments.
