    JEGS Hot Rod Heaters will keep you warm on those cold days, simply connect plumbing and wiring directly to your cooling system for immediate heat. The blower unit blows fresh air through the heat exchanger, elevating the air temperature, which then exits through the outlet louvers adding strong and consistent heat to any vehicle. You can even use these auxiliary heaters as an economical alternative to replacing a worn-out or hard-to-reach heater core. Heaters are available in a variety of sizes and styles with multiple speeds and adjustable settings. Defroster and Louver/Vent kits are available separately.

    JEGS EZ Kits are designed by JEGS professionals to ensure that you get all the correct parts you need.

    Rated 4 out of 5 by from Good buy. Seems to be good quality, but the fan is pretty noisy and the tubes for the hoses are a little short when installed over a firewall mat.

    Rated 4 out of 5 by from Installation went fairly well. However the template for the firewall mounting was incorrect. I had to modify template & redrill holes ! I was not happy about the extra holes and work especially after accurately laying out template on the firewall !

    Rated 3 out of 5 by from Nice and compact So far I am pleased with the unit. It is compact works well. The only thing that I found was the template to install was not right. The mounting holes did not line up which gave me some frustration.

    Is it real loud? Can you hook up defrost?

    Asked by: 1956 tow mator
    Blower fan is no louder than any standard automotive heater fan. With ducting you could install defrost.
