can some one please tell me what this is and can i take it off ? coz its in the way

It's a knock sensor.

Take it off if you are running after market management. Or move and mount elsewhere if you are running standard ECU.

No.

It's just a threaded blind hole in the block. The sensor is just a microphone.
