it was old - gold price , now they are more expensive ,as mentioned before . they are updated over 12 times afaik . can be replaced one or two , just dealer dont want to waste their time and says to replace all of them . have done lot cars, by one or two injectors and they going just fine ,of course its nice to replace all at once
