These wires are slightly thicker (by 0.5mm) than the OEM and have worked phenomenally so far! I have both these MSD spark plug leads and MSD coils and they both work really well together! As for the increase in gas mileage, personally I haven't noticed much of a difference, maybe 0.2mpg? But throttle response is slightly better than before, although not enough to notice. To unleash the beast of a predator in combination with MSD wires and coils, an upgraded choke from BBK and CAI would really bring out these MSDs.
