This Dual High Output Radiator Fan Assembly allows true Dual Fan performance in a package the size of others Single shrouded fans. Featuring an aluminum shroud measuring a tidy 24 inch wide by 15-1/2 inch top to bottom and only 4-1/2 inch in overall depth to offer an adjustable yet precision fit, it uses two IP-68 certified waterproof/dustproof 12 inch electric fans to provide a powerful one-two 3750 CFM punch to a hot engine. The natural, non-finished aluminum shroud gives the user the freedom to polish, anodize, paint, or simply leave it raw to create a truly custom look at a reasonable price.
