Hayden Blue Streak HD Electric Fans

Hayden Blue Streak HD electric fans help improve fuel efficiency, horsepower and extend the life of your engine and transmission. Today's modern engines operate at very high temperatures to meet emissions regulations, and the range between normal operating temperatures and overheating is not that great. If the fan fails, it can cause severe damage to your engine. These premium fans can restore the performance of your cooling system, thanks to their unique profile. They can be installed either as a puller or pusher, and feature a quiet, high-flow "S" blade design, full-finger guard shroud, and powerful high-output DC motor that's built and tested to quality specifications. Features and specs include: * Heavy-duty 4-pole motor for long life and more torque * 8 in. staggered angle high-velocity blade for maximum air flow * 500 cfm * Universal fan (not a direct OE replacement) * Includes mounting kit for ease of installation Show Less
