Depends when you have taken them out... personally looks more like cold start on newish plugs...
they were on the car for two weeks!
Looks about right... they should start to go brwonish colour if running ok... what makes you think you have a problem?
i just want to be sure that im not running rich again like before i just change my blow off to forge 007p
well no more backfire i hope its ok now
What model/year of car?
1.8t agu 98 with few mods chip ,downpipe,open ,air filter, tip
