The AIR FLOW RESEARCH Gen III Hemi 212cc Right-Hand Cylinder Head (AFR 2522) is a precision-engineered aluminum cylinder head designed for Gen III Hemi engine builds requiring maximum flow efficiency and chamber optimization. This CNC-assembled unit combines a 212 cubic centimeter intake runner volume with a 73 cubic centimeter combustion chamber, delivering the volumetric efficiency serious engine builders demand for high-performance applications.
The head features 2.125-inch intake and 1.650-inch exhaust valve sizes paired with 1.290-inch valve springs, engineered for sustained high-RPM operation. The straight-plug design simplifies ignition system integration, while the aluminum construction provides weight savings critical for performance platforms. Each head arrives fully assembled and ready for installation on the passenger side of Mopar Gen III Hemi applications. The specific chamber volume and intake pathway dimensions are optimized for fuel charge velocity and combustion efficiency, translating to measurable gains in horsepower and torque over stock configurations.
This cylinder head serves engine builders, performance shops, and Hemi platform enthusiasts building high-output street or competition engines. It's specified for vehicles where stock breathing capacity limits performance potential. The Gen III Hemi platform—found in modern Dodge and Chrysler vehicles, as well as marine and industrial applications—benefits significantly from aftermarket cylinder head selection when paired with complementary intake manifold, fuel system, and tuning modifications.
AIR FLOW RESEARCH (AFR) is recognized in the performance engine building community for CNC port work precision and chamber design focused on flow characteristics over competition engine classes. The 212cc intake volume on this head positions it in the mid-range for Hemi applications—aggressive enough for serious power without sacrificing low-end torque delivery that larger displacement intakes sometimes compromise.
