Key Features

• Nitride-coated valve surface for added wear resistance and corrosion protection
• 34 mm valve head diameter for application-specific intake valve fitment
• 6 mm stem diameter and 99 mm overall length
• Premium grade type for OE-style replacement use
• 1 lock groove design
• Direct-fit intake valve for selected 1992-1997 Acura, Honda, and Isuzu engines

Detailed Description

The DJ Rock IV350 intake valve is engineered for precise air-fuel charge control in the combustion chamber. Its nitride-coated construction helps the valve withstand heat, friction, and corrosion in demanding engine environments, while the specified head diameter, stem diameter, and overall length support correct valvetrain geometry. This part number, IV350, is listed for 1996-1997 Acura SLX, 1994-1997 Honda Passport, 1993-1997 Isuzu Rodeo, and 1992-1997 Isuzu Trooper intake valve applications. This part cross-references 021-3464 for the same application.

What This Part Helps Address

• Low compression caused by a worn or damaged intake valve
• Rough idle related to poor intake sealing
• Loss of power from inefficient cylinder filling
• Valve wear from heat and repeated opening cycles
• Corrosion or surface damage on the intake valve face and stem

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and lock groove count before installation. Match the vehicle application exactly, since IV350 is specific to the listed Acura, Honda, and Isuzu models. During cylinder head service, inspect valve guides, valve stem seals, and related valvetrain components for wear before reassembly.

Quality Assurance

DJ Rock positions this intake valve as a premium-grade replacement built to meet or exceed OEM quality expectations. The nitride-coated finish and heat-resistant material selection are intended to support durability in high-temperature engine operation.
