Just got a 1997 Taurus LX Duratech DOHC V6 with 91,000 miles. Red metallic with tan leather. Moo-yeah.

Looks like it was fairly well maintained. Some of the fuel pipework is bright and shiny, obviously recently replaced and I found some old oval gasket under the hood which matches up with one of the connections, bolstering the replacement theory.

Without any service records I've no idea when the plugs and wires were last replaced, if ever. Looks like the only way to get at the back bank (with the engine in the car) is to remove the upper intake manifold.

Soooo, before I take the plunge on yanking bits off the engine that shouldn't have been designed so stupidly, does anyone have any info on spark plugs actually proven to provide higher MPG? Especially if tested in a Duratech V6 in a 3rd gen Taurus.

I don't mean manufacture claims, I want real world tests by real world people.

Major, if any, aero mods not going to happen because 99.999% of my driving is in town at 20~35 MPH.
