Nissens 606448 Aluminum Engine Radiator with Brazed Cooling Fins

The Nissens 606448 is a direct-fit, full-aluminum engine cooling radiator engineered to OE specifications. Constructed using advanced Controlled Atmosphere Brazing (CAB) technology, this radiator delivers reliable thermal performance and long-term durability as a replacement for Porsche 911, Boxster, and Cayman applications.

Nissens follows their "First Fit" philosophy, meaning all necessary hardware — including gaskets and seals — is included in the box for a straightforward, time-saving installation. The unit ships without a radiator cap, so the existing OE cap can be reused.

Key Features:

• Full aluminum construction with brazed cooling fins for superior heat dissipation
• Core dimensions: 366 x 340 x 42 mm (approx. 14.4" x 13.4" x 1.65")
• Includes gaskets and seals — no cap included
• Double-folded fin design reinforces the core and increases total heat exchange surface area
