ISR Performance Radiator Fan Shroud Kit - Nissan SR20DET S13

The ISR Performance Radiator Fan Shroud Kit for the S13 SR20DET delivers focused airflow to your radiator with dual 12" electric fans in a lightweight shroud designed as a direct OEM fit. Lighter and more durable than the factory plastic shroud, with the airflow geometry you actually want for a hard-driven SR.

What It Does

The shroud channels air through the radiator core instead of letting it spill around the edges, and the dual 12" electric fans pull more air through at low speed than the OEM mechanical setup. Net result: better cooling at idle and crawling speed, which is where 240SX builds typically run into heat issues. The shroud also keeps the fan blades safely contained away from the radiator and engine bay accessories.

Fitment

Direct OEM fit on the Nissan S13 240SX (1989-1994) with the SR20DET swap. For KA24-equipped S13s, see our KA-specific shroud kit (IS-FS-KAS13).
