It is a high-current generator. The engine's computer sends a signal to the coil so that it can boost the energy that will be conducted through some special wires to the spark plugs and, in one of its ends, the spark that will later spark the fuel mixture inside of the cylinders will be generated.
It will work good but start blowing hot air but the whole coil under the hood stays cold the top part and the bottom and the parts that runs to the air condition coil it don't need any freon and the fan works
