I'd go with a new set of wires, a good set of NGK's, and if you are looking into forced induction or nitrous, an MSD blaster cap, and Blaster-series coil. I have a full setup on my D-series, and I love it. Original cap and coil were fried, so I decided to go aftermarket. I wouldn't suggest a coil and cap for a basically stock motor, as it's not needed - however.
