|>DUAL ELECTRIC FANS FOR DIESELS
What: This dual electric-fan system might seem counterintuitive for cold weather, but in winter, diesel engines take longer to warm up. Go ahead and double that time for the interior. This works in ’94-’09 Rams with the Cummins.
Some tech: The direct-fit, bolt-on setup features a variable speed controller so that you can decide at what temperature the fans activate.
Bonus info: Did someone say also a bump in fuel economy and more horses? They said: “Increase the engine power delivered to the wheels when the factory belt-driven fan is replaced with this electric fan system.” Price: Around $520. How to get: Flex-a-lite, flex-a-lite.com
