Detailed Product Description

The CSF radiator 3876 is engineered with a 1 1/4 inch thick aluminum core that measures 16 5/8 inches wide and 25 3/16 inches long, providing a durable and efficient cooling surface. The plastic tanks are designed in an OEM style to ensure compatibility and durability.
