KacuYelin VVT Oil Control Solenoid Pair for Hyundai & Kia 2.0L/1.8L (918033/918034) — Direct-Fit, Corrosion-Resistant

KacuYelin 2-piece VVT oil control solenoid set (918033 & 918034) is a direct-replacement variable valve timing actuator designed to restore precise oil flow control for compatible Hyundai and Kia 2.0L/1.8L engines.

This pair of oil control valves (also called VVT solenoids) replaces worn or faulty units to help the engine management system adjust cam timing accurately. Each solenoid matches common OEM connectors and mounting points and is built with corrosion-resistant finishes, premium O-rings, and a silicon-steel core for reliable electrical response. Fitment covers many Elantra, Kona, Sonata, Tucson, Veloster and several Kia models from 2012–2024—confirm compatibility using your vehicle details before ordering.

Which vehicles and engines will these solenoids fit?

These VVT solenoids are engineered for specific Hyundai and Kia naturally aspirated 1.8L and 2.0L engines and several hybrid variants. They replace the OE part numbers listed with equivalent electrical and mounting interfaces. Always verify your year, model, engine size and aspiration type with the fitment tool or your service manual.

• Common Hyundai fits: Elantra (2012–2020 variants), Kona (2018–2020), Sonata (2016–2020 non-turbo), Tucson (2017–2021), Veloster (2019–2021 natural aspirated)
• Common Kia fits: Forte/Forte5 (2014–2023 ranges), Forte Koup, Optima (2017–2020 non-turbo), Soul (2012–2023), Seltos (2021)
• Compatible OEM references: 918-033 / 918033 / 918-034 / 918034 and other listed OEM codes

How do these solenoids differ from worn factory units?

Replacement units are built to address common failure modes like oil leaks, slow electrical response and corrosion. KacuYelin solenoids use electrophoretic coating and upgraded O-rings to resist oil degradation and sealing failures. The silicon-steel core gives quicker reaction to ECU commands compared with degraded originals.

• Electrophoretic coating for improved corrosion resistance
• Premium O-rings to reduce oil seepage
• Silicon-steel solenoid core for faster, more accurate actuation

What should I expect during installation and performance?

Installation is typically straightforward for mechanically skilled DIYers or technicians because electrical connectors and mounting points follow OEM dimensions. You may need basic hand tools and a torque spec from the vehicle manual. After fitting, the engine management system should be able to vary cam timing normally; symptoms such as rough idle or timing-related codes can indicate a faulty VVT solenoid.

• Direct-fit connectors and mount positions mimic OEM parts
• Standard hand tools required; follow factory torque specs
• Check for stored engine codes and test drive to confirm normal operation

Are these parts quality-assured and what do the numbers mean?

KacuYelin manufactures these solenoids in TS16949-certified facilities and applies multi-stage testing during production. The listed OE numbers (for example 24375-2E100, 24355-2E100, 22110-2E000) help you cross-reference the correct replacement. Use your vehicle information to confirm the correct part variant before purchase.

• Produced in TS16949-certified lines with quality checks
• Multiple OE references included for cross-checking
• Sold as a 2-piece set to replace both VVT control valves where applicable

Who is this for: This 2-pack of KacuYelin VVT oil control solenoids is for owners and mechanics servicing Hyundai or Kia 1.8L/2.0L engines who need a direct-fit replacement for timing control components. It's suitable for those troubleshooting timing-related drivability issues, performing preventative maintenance, or restoring proper VVT operation after an electrical or oil-leak failure. Confirm fitment with your vehicle's year, model and engine details before ordering.
