I can't find any manufacturer for spark plug wires except for cheap autozone duralast wires. I've tried NGK and magnecore and accel but they do not have plugs listed for either the mercury capri or mazda 323. I found some NGK wires for the 323 but they have been discontinued!!! Does anybody have any ideas on how I should go about this problem? I've thought about ordering custom plugs but I'm not exactly sure what kind to get. The order forms have too many options that I do not quite understand.
