The Kia G4LC is a 1,497 cc, inline‑four turbo‑petrol engine produced from 2018 to present. It features a dual overhead camshaft (DOHC) design with 16 valves and gasoline direct injection (GDI). This compact powerplant delivers 150 kW (204 PS) and 265 Nm, utilizing a twin-scroll turbocharger for strong, responsive performance.
Fitted primarily to the third-generation Kia Ceed (CD) and XCeed, the G4LC was engineered for drivers seeking sporty dynamics and efficiency in a compact package. It targets enthusiasts wanting spirited acceleration without sacrificing daily usability. Emissions compliance is achieved through a close-coupled catalytic converter and particulate filter (GPF), meeting Euro 6d-TEMP standards.
One documented concern is carbon buildup on the intake valves, a known characteristic of direct-injection engines without port injection. This issue, referenced in Kia technical service bulletins for the CD Ceed GT, can lead to rough idling and reduced performance over time. Kia recommends periodic intake cleaning procedures as preventative maintenance.

The twin-scroll turbo provides strong, lag-free torque ideal for spirited driving but requires adherence to 10,000-mile oil change intervals to maintain turbo and chain longevity. API SP 5W-30 oil is critical for protecting the direct injection system and timing components. The engine is prone to intake valve carbon buildup; periodic walnut-blasting or chemical cleaning is recommended per Kia TSB. High-quality 95 RON (or higher) fuel is advised for optimal performance and to minimize carbon deposits.
Oil Specs: Requires API SP specification (Kia Owner's Manual). ACEA C2 is an acceptable equivalent for low-SAPS requirements.
Emissions: Euro 6d-TEMP certification applies to all 2018–Present G4LC models (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under SAE J1349 standards. Output is consistent across all model years (Kia PT-2023).

The Kia G4LC was used in Kia's CD platform with transverse mounting. This engine received minor ECU updates during its production run but no major mechanical platform-specific adaptations. All applications are documented in OEM service manuals.
Locate the engine code stamped on the front of the cylinder block, near the alternator (Kia Workshop Manual CD). The 8th digit of the VIN for G4LC-equipped vehicles is typically 'G'. The engine is visually identified by its compact size, aluminum DOHC cylinder head, and the prominent twin-scroll turbocharger. Critical differentiation from the naturally aspirated G4LD: The G4LC has a direct fuel rail and high-pressure fuel pump on the cam cover. Always verify the engine code stamping before ordering parts.
The G4LC's primary reliability consideration is intake valve carbon buildup, a common trait of direct-injection engines. Kia service data indicates this is a routine maintenance item rather than a failure, while owner reports frequently cite the need for cleaning to restore performance. Neglecting oil changes or using low-quality fuel accelerates carbon formation and can lead to timing chain wear.
