DJ Rock IV814 Engine Intake Valve

Overview

The DJ Rock IV814 engine intake valve is a direct-fit replacement for a wide range of Audi and Volkswagen applications. It is built for precise airflow control in the combustion cycle and uses a nitride-coated finish to support durability under heat and wear.

Key Features

• Direct-fit intake valve for application-specific engine service
• Nitride-coated surface for improved wear resistance and corrosion protection
• 33.8 mm valve head diameter, 5.96 mm stem diameter, and 103.7 mm overall length
• 3-groove design for compatible valvetrain assemblies
• Premium-grade construction for demanding engine environments

Detailed Description

The IV814 is an engine intake valve designed to open at the correct camshaft timing so the air-fuel charge can enter the combustion chamber efficiently. Its nitride-coated construction helps reduce friction and supports stable operation under repeated thermal cycling. This part number, IV814, is listed for multiple Audi and Volkswagen models, including Audi A4, A6, A8 Quattro, S4, S5, S6, S8, Q5, Q7, SQ5, A5 Quattro, A7 Quattro, and Volkswagen Touareg applications. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Restoring proper intake valve sealing after wear or heat damage
• Addressing loss of compression caused by a damaged valve
• Correcting rough running from poor cylinder breathing
• Replacing a valve with worn stem or head dimensions
• Supporting engine repair during valvetrain service

Installation Notes

Verify valve head diameter, stem diameter, groove count, and overall length before installation. Match the part to the exact engine application and inspect related valvetrain components during service. Professional installation is recommended for cylinder head work and final valve clearance checks.

Quality Assurance

DJ Rock lists this intake valve as a premium replacement built to meet or exceed OEM quality standards. The nitride-coated design and application-specific fitment support consistent performance in high-temperature engine operation.
