Hyundai SONATA 08 (2007-2013) 2007-2013 G4NA G4NB Engine Parts G4NA 2.0 G4NB OEM 22100-2E001 Cylinder Head Kia 1.8L 2.0L – OEM 221002E001

Product Overview: This complete cylinder head assembly is manufactured for Hyundai and Kia G4NA and G4NB 1.8 and 2.0-litre petrol engines, the modern four-cylinder family used in sedans, SUVs and compact passenger cars. It is supplied fully assembled with valves, guides and seats installed and is machined to original equipment tolerances, providing a reliable replacement for a cracked, warped or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade material and CNC-machined for accurate deck flatness, correct 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, and the cam carrier surfaces are finished for correct bearing clearance in the DOHC layout. Intake and exhaust flanges are precision machined for reliable gasket sealing, and cooling passages follow the factory design.

Vehicle Compatibility: This head fits Hyundai Sonata 08 (2007-2013), iX20 11 (2010-2015), Eon 11 (2011-2018), i30 16 (2014-2017), Veracruz (2006-2013) and iX35 Fuel Cell (2013-2018) models, plus related Kia platforms using the G4NA or G4NB engine in 1.8-litre and 2.0-litre form. Confirm the engine code and OE reference before ordering.

Specifications: Engine code G4NA / G4NB; displacement 1.8 L and 2.0 L; inline four-cylinder petrol; material cast iron or aluminium; standard size; new condition; complete assembly; 12-month warranty; purpose replacement and repair.

OEM / Reference Numbers: 221002E001, 221002E002, 22110-2E001, 22110-2E002 and 22100-2E000. Cross-reference these numbers with the casting marks on the original cylinder head to confirm the correct variant.

Applications: Suitable for mid-size sedans, compact SUVs, MPVs and light commercial vehicles, covering routine repairs, engine overhauls, rebuilds and fleet maintenance where a factory-specification head is required.

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

Installation or Fitment Notes: Installation should be carried out by a qualified technician. Inspect the block deck for flatness and clean all mating surfaces, fit a new head gasket and new head bolts where specified, and torque in the correct sequence. Replace timing and cooling components as required, verify valve clearances and cam timing, then run the engine to operating temperature and confirm there are no leaks before road testing.
