Autolite 765 spark plug for the 1991-1996 Ford Explorer V6 4.0L and other vehicles fires the spark that ignites the air-fuel mixture in each cylinder. This Autolite spark plug is engineered for quick starts.
- Copper core center electrode for thermal control and resistance to fouling
- High nickel alloy center and ground electrodes for extended life
- High alumina multi-rib ceramic insulator for thermal conductivity and insulation strength
- Nickel-plated shell that resists corrosion
- Resistor design rated at 4000 ohm
Quick facts
- Part: Autolite 765 spark plug
- Fits: 1991-1996 Ford Explorer V6 4.0L and other vehicles
- Material: ceramic insulator
- Condition: New
Hard starting, a rough idle or a misfire can mean the plugs are worn. Those signs can also come from ignition coils, wires or fuel delivery, so with the engine off and cool, look at the old plug's tip and insulator for wear, deposits or cracks first. A shop can test the ignition system.
