DJ Rock IV217 Engine Intake Valve

Engine Intake Valve Overview

The DJ Rock IV217 engine intake valve is a direct-fit replacement built for precise airflow control in the combustion cycle. It is engineered for applications that require a nitride-coated intake valve with OEM-level dimensional accuracy.

Compatible with Acura Integra, Honda Civic, and Honda Civic del Sol applications, this intake valve supports proper cylinder filling and stable engine operation. The IV217 part number is used for fitment-specific replacement needs where the original valve matches the listed dimensions and design.

Key Features

• Nitride-coated surface for improved wear resistance and corrosion protection
• 33 mm valve head diameter for application-specific fitment
• 5.5 mm stem diameter for precise valvetrain compatibility
• 102.3 mm overall length for direct-fit replacement use
• Premium-grade intake valve construction

Detailed Description

The DJ Rock IV217 intake valve is manufactured as an application-specific replacement for engines that use the listed valve dimensions and intake-valve configuration. Its nitride-coated construction is intended to reduce friction and improve durability under repeated thermal and mechanical loading. The 1-groove design, 33 mm head diameter, 5.5 mm stem diameter, and 102.3 mm overall length make this part relevant for precise valvetrain service on Acura Integra, Honda Civic, and Honda Civic del Sol engines. The IV217 part number should be matched carefully to the original valve specification before installation.

What It Helps Address

• Worn or damaged intake valve sealing surfaces
• Loss of compression from valve wear or distortion
• Restricted airflow into the combustion chamber
• Valve replacement during cylinder head service
• Restoration of proper valvetrain geometry with the correct dimensions

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and groove count against the original component before assembly. This intake valve is listed as a direct-fit replacement, but cylinder head condition, valve guide wear, and seat condition should be inspected during service. Professional engine assembly practices are recommended for final fitment and sealing checks.

Quality Assurance

DNJ Engine Intake Valves are manufactured to meet or exceed OEM quality standards. The IV217 uses heat-resistant alloy construction with a black nitride coating to improve wear resistance, reduce friction, and support long-term durability in demanding engine environments.
