Detailed Description

Melling V3172 is an intake valve engineered for engines that require accurate fitment and stable performance under heat and load. The steel valve material, 107.0 mm overall length, and coated finish support consistent operation in stock rebuilds and maintenance work. This part number is used across multiple Honda and Acura applications, including Honda Accord, Honda Element, Honda CR-V, Honda Civic, Acura RSX, Acura TSX, and Acura RDX, making it a practical choice when replacing a worn intake valve in compatible engine assemblies. Part number V3172 is also referenced by cross-reference numbers such as DNJ IV216 and 10-03031 for the same application.

What It Helps Address

• Loss of intake valve sealing from wear or heat exposure.
• Reduced compression caused by a damaged or fatigued valve.
• Valve train service needs during engine rebuilds.
• Replacement of a stock intake valve with matching geometry.

Installation Notes and Tips

Verify valve head diameter, stem diameter, seat angle, and overall length before installation. Confirm the engine application against the vehicle service information for the exact Honda or Acura model and year. Because this is a standard replacement intake valve, it should be matched carefully to the original valve specifications during cylinder head service.

Quality Assurance

Melling uses precision engineering, controlled material selection, and advanced manufacturing processes to produce intake valves with high fatigue strength and heat resistance. The V3172 is built to meet the specifications required for durable engine service in stock and performance-oriented applications.
