I'm currently running two of my car's normal injectors, and two TD4 injectors while the others are in for refurbishing/repairs. Although it is smooth, the car is sluggish as hell, and thirsty as fukc! 10k per liter town driving![]()
Then they're probably different, flow rate, nozzle spray angle, impedence etc could vary. Unless the ones in the TD4 have the exact same bosch part# I would not assume them to be identical.
