Mine are $2.29 a piece. About $18 for all 8. But I have the 5.8. Yours should be close to that. Bring a 20 spot to the parts store and they should fix ya up.

I used Ford Motorcraft copper plugs and it cost me about $20, but I live in Northern Canada and I have the 300 straight six.

She was happy when I changed them with new copper cores. Have seen people post about problems after installing platinums or those E3 plugs...

When I first got my truck, the P.O had put in NGK Iridium plugs when he parked it. It was a 2 hour drive home when I put the plates on it, pretty sluggish ride and not much get up and go past 3rd gear. Read up about the plugs, swapped em out and problem solved!

Autolite 25 or Motorcraft SP450
