ISR Performance Aluminum Radiator - Nissan 240sx 89-94 w/KA24DE

Not every S13 gets an engine swap. For the cars still running the KA24, the ISR Performance aluminum radiator for the 1989 to 1994 Nissan 240SX S13 with KA24DE replaces the aging factory radiator with a lightweight TIG welded aluminum unit that drops straight into the stock location.

Why upgrade a KA radiator

Original 240SX radiators are now decades old, and plastic end tanks do not last forever. Beyond simple replacement, a KA24 that has picked up a turbo kit, bigger injectors or regular track use produces more heat than the stock core was designed for. An aluminum radiator gives that engine the margin it needs without the cost of the top-tier brands.

Specifications

• TIG welded aluminum construction
• Lighter than the OEM radiator
• Direct drop-in for the S13 chassis
• Core size very comparable to the more expensive Koyo radiator
• Cooling efficiency on par with other aluminum radiators at a lower price point

Fits

Recommended companions

ISR makes a matching S13 KA24DE fan shroud kit with dual 12 inch fans, plus silicone KA24 radiator hoses in blue or black, which together make a complete cooling refresh for a KA-powered S13.
