DJ Rock IV802 Engine Intake Valve

Engine Intake Valve for VW and Audi

The DJ Rock IV802 is a premium nitride-coated engine intake valve built for direct-fit replacement in a wide range of Volkswagen and Audi applications. With a 33.9 mm valve head diameter, 5.98 mm stem diameter, and 103.9 mm overall length, it is specified for precise valvetrain service on turbocharged and naturally aspirated engines that require accurate airflow control.

• Nitride-coated surface for improved wear resistance and corrosion protection
• 33.9 mm valve head diameter, 5.98 mm stem diameter, 103.9 mm overall length
• 3-groove stem design for confirmed application matching
• Premium-grade intake valve for engine rebuild and repair work
• Direct-fit replacement for select Volkswagen Golf, GTI, Jetta, Passat, Tiguan, Beetle, Eos, CC, Golf SportWagen, Golf Alltrack, and Audi A3, A4, A5, A6, A8, Q5, Q7, TT, TTS, TT RS, RS7, S6, S7, S8, and allroad models

Built for Valvetrain Accuracy

Part number IV802 is engineered to open at the correct camshaft interval so the intake side of the cylinder head can draw in the proper air-fuel charge. The nitride-coated alloy construction helps the valve withstand heat, friction, and long-term mechanical stress, which is important during engine rebuilds and cylinder head service. This intake valve is used across many 2005-2019 Volkswagen and Audi platforms, including 2012-2018 Volkswagen Jetta, 2015-2018 Volkswagen GTI, and 2011-2015 Audi Q5 intake valve applications.

This part cross-references related intake valve applications for the same engine family.

Common Repair Uses

• Restores intake sealing after a burned, bent, or worn valve
• Addresses low compression caused by valve face or stem wear
• Supports cylinder head rebuilds after overheating or high-mileage service
• Replaces a damaged intake valve in Volkswagen Golf, Jetta, Passat, and Audi A4/A5/Q5 engines
• Helps correct rough running, misfire, and loss of power tied to valvetrain wear

Installation Notes

Verify valve head diameter, stem diameter, overall length, and groove count before installation. Match the application notes carefully, especially on Volkswagen Eos, GTI, Jetta, and Passat models that list timing belt or timing chain engine variants. Cylinder head inspection, valve guide condition, and valve seat condition should be checked during service to confirm proper sealing.

Quality Assurance

DJ Rock IV802 is manufactured to meet or exceed OEM quality standards and uses heat-resistant alloy construction with a black nitride coating for added durability in demanding engine environments.
