Suzuki Vitara SX4 2017+ 2.0L (Second Generation) IGNIS SUV (17.08-) J20A Motor J20A Engine Cylinder Head 11100-65G02 11100-65G03 Aerio – OEM 11100-65J01

Product Overview: This complete cylinder head assembly is manufactured for Suzuki J20A 2.0-litre petrol engines, the four-cylinder unit used in the Vitara, SX4, Aerio and Ignis families. It is supplied as a fully assembled replacement with valves, guides and seats installed and is machined to original equipment tolerances, making it a practical solution for a warped, cracked or valve-damaged original cylinder head.

Key Features: The casting is produced from high-grade aluminium alloy and CNC-machined for accurate deck flatness, correct valve seat concentricity and consistent 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 valvetrain, and the intake and exhaust flanges are precision machined for reliable gasket sealing and correct manifold alignment.

Vehicle Compatibility: This head fits Suzuki Ignis SUV second generation (August 2017 onwards) and Alto (2004-2009) models, plus related Suzuki Vitara, SX4 and Aerio applications equipped with the J20A engine. Because several Suzuki models share this engine, always verify the engine code, casting number and OE reference against the original component before ordering.

Specifications: Engine code J20A; displacement 2.0 litres; inline four-cylinder petrol; material aluminium alloy casting; standard size; new condition; complete assembly; 12-month warranty, or 12 months and 20,000 km in some conditions; purpose replacement and repair.

OEM / Reference Numbers: 11100-65J01, 11100-65J00, 11100-65G00, 11100-65G01, 11100-65G02 and 11100-65G03. Match these references against the casting marks on the original head to confirm the correct variant.

Applications: Suitable for compact SUVs, crossovers, small sedans and hatchbacks, covering everyday repairs, engine rebuilds, workshop overhauls and fleet maintenance where a factory-specification 2.0-litre 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 separately reconditioning valves, guides and seats. A complete unit reduces downtime and simplifies the overhaul.

Installation or Fitment Notes: Entrust installation to 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. Replace timing chain components and coolant during the job, verify valve clearances and cam timing, then run the engine and check for leaks before road testing.
