Recently I had a problem with the injectors which reulted in part of the wiring burning out. I purchased a seconhand set of 4 off a chap breaking a 2005 motor. Now comming to fit them the guy doing the job says that the ones I bought are wrong they are blue plastic type and the ones in the motor are metal, my motor is a year 2000 model. Can anyone help as I thought that these are a modification on the old type?
