"Those 3 prong SP are crap IMO."
Notice the Platinum +4 on the side... Sorry, just an observation. Anyway, if the edge of the tip of the eletrode is still fairly sharp which you can't tell from the picture, and the ground straps, or whatever you want to call those 4 things aren't to worn and have a sharp edge then you are probly okay. Sparks like a nice sharp edge and that is where they are worn. I don't know if you can check the gap with all those stupid "ground straps" or whatever but that is another way to check the condition of your plugs. If the gap is excessive it works your ignition system harder and might cost a little power. My recommendation is to go ahead and switch to the iridium because they have been known to increase power and they will last longer than your car.
