I got a 325 is 1987 and the spark plug wires are not eom so I want to buy new ones. I went to an auto part and the guy tell me that I can use an e wire set that are cheaper than the i wire set. the problem is that the i wire has an extra cable that goes to a sensor or something like that and the e wire set don’t has it so my question is If I buy an e wire set is going to affect the performance of the car because it doesn’t has the extra wire to the sensor????
