The spark plug gap for a 1998 Ford Explorer (V6 and V8 engines) is .054"
One of the available engines in a 1998 Ford Explorer ( 4 door ) was the 5.0 liter ( 302 cubic inch ) V8 , so YES
I believe that is in the back of the alternator

No , the 5.0 liter V8 engine in a 1998 Ford Explorer was used with either rear wheel drive or all wheel drive ( that has no LOW range on the transfer case )
Not for the 2011 and newer Ford Explorer 1996 to 2001 model years of Ford Explorer , the 5.0 litre V8 was available 2002 to 2010 model years of Ford Explorer , the 4.6 litre V8 was available
On a 1998 Ford Explorer XLT For the 4.0 litre Single Over Head Cam , V6 , and the 5.0 litre V8 ( bank 2 is the drivers side of the engine )
If you have a 1997 to 1998 Mercury Mountaineer or Ford Explorer with a V8 engine, you will have a 4R70W transmission.
According to the 1998 Ford Explorer Owner Guide : For the 5.0 liter / 302 cubic inch V8 engine : ( 215 horsepower at 4200 RPM and 288 lb-ft torque at 3300 RPM )
I would assume the 1997 Ford Explorer is heavier than the 1998 Ford Crown Victoria ( especially if the Explorer is 4X4 or AWD or has the 5.0 liter V8 )
EPA ratings are 14 City and 19 Highway. The actual average MPG you get will depend on many factors. Climate, elevation, load, how you drive, tire pressure, etc. Anyway you look at it, this vehicle does not get good MPG.
