I have a 1994 3.8L v6 Mustang. currently I have bosch fusion spark plugs and was wounder if anybody knew were i could some E3 plugs or even if they made some for that year and model. Also, would it be at my advantage to switch or stay with the plugs i have now.
I did try the E3 plugs and they worked fine for a week and then fouled. E3 plugs are not for our Mustangs. You have two options: 1)Get Platinum plugs. They are recomended by Ford. They last longer. OR 2)Get copper plugs. They give you better spark but have to be changed more often.
Our Mustangs use: Motorcraft, Autolite, or NGK- Stick with these.
I use Autolite Copper Core Resistor plugs myself.
Good Luck!!
