ok, today i went to replace my spark plug wires i recieved yesterday. as i disconnected them from the ignition coil, i notice that #3 coil is rusted. not the wire the actuall coil is rusted, but just #3. does this need to be replace immediately? am i losing power cause of this? and what's the best ignition coil to replace it with? also i ordered it from modern performance their magnecore blue 8mm wires. i mention this because the stock wires 1 and 4 are the same legnth as well as 2 and 3 are the same lentgh. for the magnecore that i recieved, 1 out of the 4 do not match up to the stock wire. are the neons like this? i feel i recieved the wires for the neons.
