Instant Savings Isr Performance Aluminum Radiator Nissan 240sx W/sr20 1989-1994 | Is-240sr-rads13 - Priority Shipping [N3ntwG5g]

Fitment:

Radiators are Chassis specific not motor specific. 

Part Number: IS-240SR-RADS1X

Note: ISR orders might take a day of processing. If you need it sooner, contact us directly.

All ISR performance radiators feature a TIG welded lightweight aluminum construction. This Radiator is a perfect direct drop in upgrade to compliment your vehicle. Whether you are replacing your old OEM radiator in your daily driver or looking for a more efficient radiator for your increased power and track use the ISR Performance radiator is proven to withstand the test. With comparable quality and cooling efficiency to other radiators on the market the ISR Performance radiator is a great inexpensive alternative.

This unit is very comparable in size to the more expensive Koyo units. 

We highly recommend doing this upgrade when swapping in the motor, or soon after. Stop cooling issues before they start! 

Whats in the box:

  • 1x Radiator
  • 1x Radiator Cap
