Before using, it's better to read the instructions first. After reading, If you conclude that they will prove helpful, you may use them. Otherwise, don't!

are you facing problems?

My questions is same.. is it required after certain mileage or depend on symptoms only ? Service guys always try to lure you to spend more ... similar thing with throttle service i guess.. this isn't required on 5k every 5k service, is it ?

[Xulfiqar]

no its not, and neither is throttle body service. Do not do ultrasonic cleaning of the injectors either unless they are physically clogged.

The flow rate changes after being cleaned out - this data needs to be considered when reading ECU parameters.

Well....i noticed that only sometimes my engine sound changes for a very short time from smooth to rough....just like turbulence in a flight....but its for a very short duration and sometimes with a.c on.....but it recovers automatically....there is no major issue....i just thought being driven 150k km....may b injectors need to clean

nopes, you need to first do some diagnosis to determine if you actually have a fuelling problem. Injector lack of flow leads to lean condition detection by ECU, lean condition also can be from an air leak. Cleaning injectors wont fix the air leak,
