Read my spark plugs

They look normal to me. Book says they should be light tan or light gray, which yours are. Check gap and if possible see what color the spark is when it fires. Bright Blue/Blue would indicate good. Yellow/Orange would indicate bad wire or coil. Do so with either a new plug, or an inline spark tester (this being the safer option).
