These slim, reversible electric fans are perfect for additional aftermarket cooling or replacement of factory radiator fans. They can be used in a wide variety of other applications as well, including A/C condenser cooling, mounting on an intercooler to prevent heat soak during drag racing events, or cooling the radiator in a water-to-air intercooler setup. These fans include the mounting kit shown, which is used to secure the fan directly to the radiator through the fins with no additional mounting components. Why are our universal fans superior to other similar products on the market? Unlike some of the universal fans out there, these fans are fully reversible just by attaching positive voltage to the negative wire and negative voltage to the positive wire. Unlike some of the universal fans out there, our fans include the mounting feet and ALSO come with through-radiator mounting kits that sell for $5-$7 at most auto parts stores. Unlike some of the universal fans out there, our fans are only 2.5" deep at the deepest point, making them ideal for installations in cramped areas.
