Personally I would just go with factory ones. Its a ford ranger not a ferrari. Theyll try to sell you all kinds of crap like lucas cylinder clean ("tune up in a bottle") haha. dont fall for it. I would suggest however, changing the spark plug wires as well though. Easy to do and cheap.

the general consensus around here as well as other ranger resource sites is that motorcraft or autolite plugs are the way to go.

Dang seems like alot of people are changing spark plugs now. this is from another post:

This is to help clear up some things involving spark plugs on the 4.0 SOHC. Rwenzing (Bob) posted this for me on another forum:

Quote:
Originally Posted by rwenzing View Post
As described above, each individual coil within a Ranger coil pack fires a pair of plugs with opposite polarities. A Ranger with a coil pack ignition should use either fine wires (1st choice) or double plats (2nd choice) as a replacement for both polarity groups.

If you want a long change interval, don't use conventional single plats unless you can somehow get the OEM type that has the platinum on opposite electrodes AND you know which way to run the polarity. The confusion with these two issues in the field is why the factory doesn't specify conventional single plats as replacements in Rangers w/ coil pack ignition.

Using a double plat plug takes care of the polarity issue by making the plug universal. Fine wires are not as polarity sensitive as conventional single plats, so they can also be run in any cylinder.

If you have a Ford dealer look up the replacement spark plugs for your Ranger, chances are that the part number has been superseded to the superior fine wire plugs (probably with a -FM suffix).

The much thinner center electrode in the fine wire plug requires a lower firing voltage than conventional platinum plugs resulting in:

1) reduced electrode erosion
2) lower misfire rate
3) longer coil pack life
4) longer plug wire life

Also order your plugs here:

E3 plugs, ihave used them in another truck i had and they seem to boost the power a little. The plugs i took out were changed way before their time.

E3 spark plugs, i saw them advertised on the tv show gears and off road trucking programs, or research them on the internet. Definitely a high performance plug.
