While the OEM Fans are functional, they are still a design dating back to the 1980's and leave plenty of room for improvement. Electric fan technology has progressed a lot over the years and newer fans can efficiently move more air with a lower drawn on your car's electrical system. The laser cut shroud ensures the most efficient function of the fans drawing air through the radiator. The low profile dual 9-inch SPAL fans move 1180 CFM of air. The Fan & Shroud kit is designed to fit the CSF #7088 Radiator but will also fit OEM 944 NA Radiators. These fans have standard SPAL connectors but can be rewired for OEM connectors during installation.
