The manifold heater helps vaporize fuel in the intake manifold when the engine is cold. This helps with cold starts & idling until the engine reaches operating temperature. This kit allows a manifold heater to be used when rewiring your Jeep with a Painless chassis harness, using a later style manifold on an older Jeep, or if the factory relay was removed from your Jeep.
