I have a 96 Eldorado with a N/S and I need advice on best plugs and wires to use. My performance has drastically declined and I am planning on changing them myself, I need to know through your experience in these forums which are best to use.
Factory originals are the only way to go. Unless you want to do like some have done and buy the cheapies first and then buy the good stuff. If you want first class oats you pay top dollar. If you can settle for running them through the horse first they are a lot cheaper.
