What is the spark plug number arrangement on 8 cylinder Ford Crown Victoria 4.6L?
The firing order for a 4.6L Ford Modular V8 engine (like the one in a Crown Victoria) is 1-5-4-8-6-3-7-2. However, this doesn't directly translate to the physical plug location without knowing the engine's orientation in the vehicle. You'll need to consult a repair manual or a diagram specific to your year and model Crown Victoria to determine the exact plug location for each cylinder number. The physical location of the spark plugs can vary slightly depending on the year and any modifications to the engine bay.
