    Rated 5 out of 5 by from Good product If I was smarter,I would have measured the lengths for other users as I wondered before I clicked the buy button. But, they fit under the headers thru the motor mount and up to the hei. Maybe the next guy will measure

    Are all the spark plug wires the same length, or are there different lengths? I bought a set of MSD wires and they fit perfectly on the pass side of the car however all but 1 is to short on the drivers side.

    Asked by: JS Ragman
    The MSD 121-31239 wire set does not come with equal length wires.
