Sorry about that man. As I stated earlier, only 3 plugs have ever been tested side by side (remember weapon x? lol, the 25$ apiece 1hp gain plug).
stock, 103's and wx, no others.
actually running 103s in the 07, idles a tad rough but otherwise everything seems good. rough idle may be a combo of the steeda sri and plugs, have to do a little looking into on plug gap and see if that fixes it.
