Product Description

The IV325 intake valve is engineered for the combustion cycle by opening at the correct camshaft interval to admit the air-fuel charge into the cylinder. Its nitride-coated finish helps the valve withstand heat and mechanical stress, while the specified head diameter, stem diameter, and overall length support accurate fitment in the intended Chevrolet Aveo and Chevrolet Aveo5 engine applications. Use this part when replacing a worn or heat-damaged intake valve in the valve train.

Common Repair Applications

• Restoring intake valve sealing after valve face wear
• Correcting compression loss caused by a damaged intake valve
• Replacing a bent or heat-stressed valve during cylinder head service
• Addressing rough running from poor intake airflow control
• Repairing valvetrain damage found during engine teardown

Installation Notes

Verify valve head diameter, stem diameter, overall length, and lock groove count before installation. Measure the cylinder head and related valvetrain components to confirm proper clearance and seating. Professional cylinder head service, including inspection of guides, seals, and valve seats, is recommended during replacement.
