what do you think is the problem? is there any problem with the fuel injection?

thanks
if previously yan din gamit mo and walang noise, then its not fuel filter that could be causing it...
pero if that's the first time for you to use the bosch brand then it could be the new fuel filter...

possible reason, fuel filter not authentic, fuel filter part number is not the right one,

if the fuel filter is authentic and is the right part number for the 4D56,then the fuel filter is good, the engine noise may be from something else that might have just coincide with the time you change it to bosch....
