i know that i dont have a 3.0..BUT i do have a 97 F150 4.6L v8 and i replaced the plugs with autolite double platinum and im going to replace the ones in my 98' 2.5L soon with the same Autolite double platinum plugs. Im very happy with my results, get the double platinums, i think the part number is APP104 (Make sure its APP not AP, the extra P is the double platinum plug. I work at Kragen auto parts lol)
