DJ Rock EV124 Engine Exhaust Valve

Engine Exhaust Valve for Hyundai Applications

The DJ Rock EV124 is a premium nitride-coated engine exhaust valve built for direct-fit replacement in select Hyundai engines. It is engineered with a 27.5 mm valve head diameter, 6 mm stem diameter, 105 mm overall length, and a single lock groove for the listed applications.

Compatible with 1996-2000 Hyundai Elantra exhaust and 1997-2001 Hyundai Tiburon exhaust applications, this valve supports proper exhaust gas release from the combustion chamber and helps maintain consistent engine breathing. This part cross-references 021-3493 for the same application.

Key Features

• Part number EV124
• Nitride-coated surface for added wear resistance and corrosion protection
• 27.5 mm valve head diameter
• 6 mm stem diameter
• 105 mm overall length
• Single lock groove design
• Premium-grade exhaust valve for direct replacement use

Detailed Product Description

The EV124 exhaust valve is manufactured for exhaust-side valvetrain service where heat and mechanical load are highest. Its nitride-coated finish helps reduce friction and improve surface durability under sustained exhaust temperatures, while the valve material selection supports thermal stability and long-term structural integrity. For Hyundai Elantra and Hyundai Tiburon engines in the listed years, this valve restores proper sealing and exhaust flow control when the original valve is worn, warped, or heat-damaged.

Use EV124 when servicing a Hyundai Elantra exhaust valve or Hyundai Tiburon exhaust valve application that requires the specified 27.5 mm head, 6 mm stem, and 105 mm length. The direct-fit design supports accurate replacement during cylinder head repair or valvetrain rebuild work.

What This Part Helps Address

• Burnt or recessed exhaust valve sealing surfaces
• Loss of compression from a damaged exhaust valve
• Exhaust leakage caused by valve warping or thermal fatigue
• Rough running related to worn valvetrain components
• Reduced exhaust flow control in serviced Hyundai engines

Installation Notes and Tips

Verify valve head diameter, stem diameter, overall length, and lock groove count before installation. Inspect the valve guide, valve seat, and stem seal condition during cylinder head service, and confirm the replacement valve matches the exhaust position for the specific Hyundai Elantra or Hyundai Tiburon application. Professional cylinder head machining and valve seating procedures are recommended for proper results.

Quality Assurance

DJ Rock EV124 is built to meet premium replacement expectations for exhaust-valve service and is manufactured to meet or exceed OEM quality standards as described by the brand. The nitride-coated construction and application-specific dimensions support consistent performance in the listed Hyundai applications.
