ISR Performance Aluminum Radiator - Nissan 240sx 95-98 w/KA24DE

The ISR Performance aluminum radiator for the 1995 to 1998 Nissan 240SX S14 with KA24DE is a straightforward cooling upgrade for an S14 that has kept its original engine. It fits in the stock position without modification and replaces the worn factory radiator with a TIG welded aluminum core that has more cooling headroom for a built or hard-driven KA.

Highlights

• All-aluminum, TIG welded construction
• Lightweight compared to the OEM unit
• Direct drop-in fitment for the S14 chassis
• Similar in size to the more expensive Koyo radiator for the same car
• Comparable cooling performance to other aftermarket aluminum radiators, at a lower cost

Daily or track

ISR radiators are used both as replacements on street cars with failing stock radiators and as upgrades on cars seeing more power and track use. On an S14 KA24DE, the biggest benefit shows up once the car is run hard for extended periods, where the factory core struggles to keep up.

Application

Nissan 240SX S14, 1995 to 1998, KA24DE engine. S14 cars with an SR20DET swap need the ISR S14 SR radiator.

Install note

ISR suggests doing cooling upgrades proactively rather than after an overheating event. Combine this radiator with the ISR S14 KA24DE fan shroud kit and a set of ISR silicone KA24 hoses for a full system.

All ISR Performance products are designed for off-road use only.
