When my car was stock I had accel 8.8 wires, accel hot coil, accel cap/rotor, K&N air filter and either accel ugrooves or split fire plugs(can't remember which) and got almost 28mpg on the highway. My previous best was alittle over 24mpg, this was with an aod vert. I have autolights in my current engine(recommended by edelbrock). I have fms plug wires right now, my next set will be Jacobs. I remember one of the boots on the accel wires burning against my headers but I can't remember if they did with the stock headers.
