Eight spark plugs?
I had my plugs replaced this week & I can't fathom why there are eight. I have a '94 Ranger 5-speed 2.3L (?) 4-cyl, it's grossly underpowered but kinda fun to drive anyway (I can drive in circles around Chevy Suburbans). But isn't kind of overkill to have two plugs per cylinder? Or is there just something massively strange about my truck? Or am I just totally automotive inept?

Eight spark plugs?
I just changed the plugs and wires on my 1992 ranger last night. There are indeed 8 plugs and wires. The plugs on the passenger side of the engine are a piece of cake the change, the ones on the drivers side are a real pain in the neck because there are things in the way for the back two plugs.
I'm ashamed to say that it took me about 30 minutes to do the passenger side and then about 1 hour to do the drivers side. My wife wasn't very pleased to have me in the garage until 1am!! It might have been easier if I had some tools to help pull the boots. I had to use a piece of string to tie around the boot and then gently twisted them with two fingers on one hand while pulling the string on the other hand. Next time I will see if I can either buy or make a better tool to pull the boots.
I'm not complaining though. My truck has about 120,000 miles and it runs great!

Eight spark plugs?
All auto parts stores sell a sparkplug boot puller. It is almost a necessity for changing the drivers side plugs.
The Ford DIS ignition system has two sparkplugs per cylinder. The engine starts on the passenger side bank only. After the key is released to the run position, the other bank starts firing. The two sparks in each cylinder provides more efficient combustion and more power than only one by itself would.
