Packson Hyundai G4KD 2.0L Aluminum Cylinder Head | OE 22100-2G250 22100-2G051
Premium 100% Tested Cylinder Head | High-Precision New Aluminum Empty Cylinder Head for Theta II

01 | Engineering Background
The Hyundai G4KD Cylinder Head is a critical component for the Theta II engine family, powering popular vehicles like the Hyundai ix35 and Sonata. As a high-performance New Aluminum Empty Cylinder Head, it is engineered to meet the exact thermal and mechanical demands of the 2.0L DOHC architecture.
When choosing a 100% Tested Cylinder Head, you are ensuring that your engine restoration addresses the common heat-related issues of the original factory unit. Our casting process focuses on structural integrity, making this premium replacement the ideal choice for professional workshops seeking long-term durability.
02 | Quality Standards & Testing
We define quality through our 100% Tested Cylinder Head protocol. Every New Aluminum Empty Cylinder Head undergoes rigorous multi-stage validation before leaving the factory. First, an underwater pressure test is performed to identify any microscopic porosity in the Hyundai G4KD Cylinder Head casting.
Next, we conduct a precision vacuum test on all 16 valve seats to guarantee a perfect seal. This level of scrutiny ensures that your 100% Tested Cylinder Head will deliver consistent combustion pressure. By utilizing CMM digital auditing, every bolt hole and sensor port on the New Aluminum Empty Cylinder Head matches the OE 22100-2G250 standard perfectly.
03 | Material Science & Thermal Control
The Hyundai G4KD Cylinder Head is subject to intense thermal cycles. To combat this, our New Aluminum Empty Cylinder Head is manufactured from premium A356 aluminum-silicon alloy. This material is specifically chosen for its superior thermal conductivity, which allows the 100% Tested Cylinder Head to dissipate heat faster than standard aftermarket replacements.
Furthermore, the T6 heat treatment process enhances the hardness of the cast component, preventing the common issue of deck surface warping. This specialized metallurgy ensures that your Hyundai G4KD Cylinder Head remains structurally stable, even during heavy-duty operation or in high-temperature climates.
04 | Fitment & Installation
Our New Aluminum Empty Cylinder Head is designed for a seamless "plug-and-play" experience. Each Hyundai G4KD Cylinder Head is machined using diamond-tipped CNC tools to achieve an ultra-smooth surface finish. This is essential for maintaining a high-pressure seal with Multi-Layer Steel (MLS) gaskets, ensuring your 100% Tested Cylinder Head performs flawlessly.
With full compatibility for OE numbers 22100-2G250, 22100-2G051, and 22100-2G001, this New Aluminum Empty Cylinder Head simplifies the inventory needs of repair shops. Every oil gallery in the Hyundai G4KD Cylinder Head is verified for clear flow to support the Dual CVVT system perfectly.
