Hyundai I20 18 G4GC 2018–2020 Manufacturing Cylinder Head 22100-23760 Kia Coupe/Elantra – OEM 22100-23780

Product Overview: This complete cylinder head assembly is manufactured for Hyundai and Kia G4GC 2.0-litre petrol engines, a widely used four-cylinder found in sedans, coupes and compact SUVs. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, making it a dependable replacement for a warped, cracked or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade material and CNC-machined for accurate deck flatness, valve seat concentricity and matched combustion chamber volume. Valve guides and seats are pre-installed and honed for even sealing and balanced compression across all four cylinders. Cam carrier surfaces are finished for correct bearing clearance in the DOHC 16-valve layout, and the intake and exhaust flanges are precision machined for reliable gasket sealing and correct manifold alignment.

Vehicle Compatibility: This head fits Hyundai i20 18 (2018-2020), H-1 (2006-2008), Elantra and Lantra 96 (1995-2001), Trajet (2006-2008), i30 20 (2020 onwards) and Grandeur (2006-2010) models, plus related Kia Coupe, Sportage and Tiburon applications using the G4GC engine. Confirm the engine code and OE reference before ordering.

Specifications: Engine code G4GC; displacement 2.0 litres; inline four-cylinder 16-valve petrol; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 22100-23780, 22100-23760, 22100-23740 and 22100-23701. Cross-reference these numbers with the casting marks and part label on the original head to confirm the correct variant.

Applications: Suitable for sedans, coupes, MPVs, SUVs and light commercial vehicles, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance programmes where a factory-specification 2.0-litre head is required.

Benefits / Replacement Information: Fitting this assembly restores compression, corrects coolant loss and combustion gas leakage caused by cracking or distortion, and eliminates the cost of separately reconditioning the original valves, guides and seats. A complete unit reduces downtime and simplifies the overhaul.

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Clean and check the block deck for flatness, fit a new head gasket and new head bolts as specified, and torque in the correct sequence.
