+2 Spark Plugs?
+2 Spark Plugs?
Has anyone tried these yet? I'm thinking about putting a new set in my 1989 F-150 302. Any better mileage? Or should I put the ol' Motorcrafts in again?

Paul, do you know what the +4's look like? If you do, the +2's look just like them but missing 2 of the arcs. I had a friend run the +4's in his 3L Ranger, and he claims better mileage.
