Engineering for Durability

Engineered with longevity in mind, the CU2423 features design details that support sustained cooling performance. Deep extrusion headers reinforce tube-to-header joints, while central reinforcement on B-type tubes helps withstand vibration and thermal expansion. The core uses folded fin edges and thermal expansion cuts to promote stability and efficient heat dissipation across a range of driving conditions.

• Thermal expansion cuts: Controlled core growth for longer life.
• Folded fin edges: Enhanced stability and heat transfer.
• Deep extrusion headers: Stronger joints to reduce leaks from vibration.
• B-type tubes: Central reinforcement to better tolerate pressure changes.
• OE-perfect fit: Multi-fit attachments ensure broad vehicle coverage without sacrificing fit.
