| Hey all - regarding the discoloration, the old ones do have a bit of a blueish/purplish hint to the gray - enough that I thought "OK, I guess these could be "purple tops"" when ordering the replacement from Coz. I'll take a closer look tonight when I get home, and verify. I have to replace a bad coil pack or plug anyway, so I'll be in that area, and can pull some plugs to compare that #4 is not noticably blacker than the rest of the plugs. -Jake
