This was a design Ford tried on the 4 cylinder engine. The 2 plugs per cylinder was supposed to give you a more complete burn of fuel thus increasing power and mileage. When replacing the plugs, install 8 on this engine.
i have a 1988 ford ranger xlt 4 cylinder and my spark size is 42-46 hope this will help
On a 2005 Ford Ranger : The 2.3 liter Dual Over Head Cam , four cylinder engine has : ( 4 spark plugs )
There are three engines available. If it's a 6 cylinder engine, 6 spark plugs. If it's the 4 cylinder engine, 8 spark plugs.
( 8 spark plugs ) for your 2001 Ford Ranger 2.5 liter 4 cylinder ( with Fords twin plug ignition system )
The 2.5 liter 4 cylinder , that has Fords twin plug ignition system , takes ( 8 ) spark plugs
On a 2002 Ford Ranger : The 2.3 liter Dual Over Head Cam four cylinder engine has ( 4 spark plugs )
The 2002 Ford Ranger in NORTH AMERICA has a 2.3 L DOHC four cylinder engine and the spark plugs are gapped at .044 inch
Because your 4 cylinder has ( 2 ) spark plugs per engine cylinder , a total of ( 8 spark plugs ) with Fords twin plug ignition system
( 8 ) sparkplugs for the 2.3 liter 4 cylinder engine in a 1997 Ford Ranger with Fords twin plug ignition system
