am radio is particularly susceptable to EMI. you can pick up a thunderstorm 20 miles away. so good luck. the racing plugs alone will kill your am reception. you need restistor plugs and wire.

firecores are low resistance to the point where they are just resistive enough to knock down emi that will interfere with computers and electronics but for AM radio??? GOOD LUCK. Im not saying they wont work but if if it did, its on the hairy edge. they are a performance piece and thw two dont go together
