I've been meaning to change my plugs, 4.0 SOHC with 53000 miles. I searched and found the part number for one of the brands my local part store carrys, then promptly lost the information before I ordered the plugs.

Could somebody in the know post the correct part numbers for the SOHC, and someone with the capability make it a sticky, please!

 

Look up plugs for the expo not the ranger.

 

Why is there a specific part number?
Just go into your parts store, ask for Motorcraft (or Autolite) Platinum plugs and then install them.

I don't understand why it was hard to find spark plugs?

 

For the Ranger its still for the OHV not the SOHC. The books are behind.

 

Have you seen this post: https://www.ranger-forums.com/general-ford-ranger-discussion-15/oem-spark-plug-confusion-kinda-long-124841/

I was having trouble over the summer with the parts numbers, I there are several options, but most I assume, go with the double platinum. Whatever you do, don't go to the dealership, they wanted like $12 for each plug! Rockauto has the same for $2-$3 each
