I have a stock 5-speed 1997 Civic HX (D16Y5) with a magnaflow header/cat. I may replace the distributor cap, rotor & wires soon so I figure now is the best time to consider any reasonable upgrade options. I've only used NGK plugs & wires so far along with the stock cap & rotor. I havent come across any clear info on using MSD cap, rotor, wires & external coil on my D16y5. Apparently, the corresponding part # is 82913. My understanding is that the MSD setup will improve spark timing and strength for improved performance. Could this also improve fuel efficiency or at least maintain it while improving throttle response?
