Detailed Description

The DJ Rock IV312 intake valve is engineered for the intake side of the valvetrain, where accurate opening and closing timing controls airflow into the combustion chamber. This valve is compatible with 1999-2002 Saturn SC2, 1999-2002 Saturn SL2, and 1999-2001 Saturn SW2 applications. It is built with heat-resistant materials and a nitride-coated finish to help maintain structural stability under repeated thermal cycling. The part number IV312 is also referenced by cross-reference part number V1949 for the same application.

For buyers searching for a Saturn SC2 intake valve, Saturn SL2 intake valve, or Saturn SW2 intake valve, IV312 provides the specified dimensions needed for proper valvetrain service. The nitride-coated finish supports reduced friction and added surface durability in demanding engine environments.

What This Part Helps Address

• Intake valve wear from high-mileage engine operation
• Loss of sealing performance at the valve face
• Valve stem wear related to repeated heat exposure
• Reduced airflow control caused by damaged or warped intake valves
• Engine performance issues tied to valvetrain service needs

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and lock groove count before installation. This intake valve is specified for the intake position only and should be matched to the cylinder head and valvetrain requirements for the listed Saturn SC2, SL2, and SW2 model years. Professional cylinder head service procedures, including inspection of guides, seals, and mating surfaces, should be followed during installation.

Quality Assurance

DJ Rock IV312 is manufactured to meet or exceed OEM quality standards and uses a nitride-coated, premium-grade construction for durability in engine service.
