This aluminum air diversion panel is designed for the 1983-1993 square body S10, S10 blazer, S15, S15 Jimmy, Syclone, and Typhoon trucks.
Made from 6061 aluminum, it forces more airflow thru the radiator for lower operating temperatures. It also serves as a nice panel to clean up the engine bay, or set tools on while making a repair.
No drilling is required to install the panel.
