only when there is a problem as reported by the fault codes. With engines controlled by the ECM the voltages that are required to operate spark plugs is very high ( in excess of 60.000 volts) This in turn means that the current flow across the electrodes of the plugs is minimal and so the electrodes do not burn as they did in years gone by. There are manufacturers today that fit v6 engines in the engine bays where the rear 3 plugs cannot be easily reached and so they fit platinum plugs and recommend that they never be changed. It really is a preference thing but as the ECM continually tunes the engine (hundreds of times a minute) tune ups are basically a thing of the past and any problems will be recorded in the fault codes.
