A detailed installation manual with pictures are included so it was very straight forward job. It took about 30 minutes.

Before
After
It was not in the installation manual but I have zip tied the cables to the intake pipe.
I did not expect power increase but instead, I want more sharp response of the engine. I have done some 5000 km after installation, I feel engine response is more sharper in any RPM and more powerful in the higher RPM than the OEM air cleaner box. Also intake air temperature is lowered. Thus more molecules of oxygen in the cylinder = more power.
As you see in the picture, I have fitted HKS BOV with a custom made adapter to fit into the OEM charge pipe.
After the installation, the sound of sucking in the air and the sound of the turbo is heard form inside the car. Also, sometimes I can hear the back turbine sound. I am not sure how you call this sound in English.
It is not my car but the sound is like this.
