Hi,
I HOPE YOU CAN HELP, I AM TRYING TO FIND OUT THE CORRECT PLACE TO PIPE IN THE HHO IN MY NISSAN 3.2 LTR TURBO DIESEL ENGINE.
Is it into the air filter if so then it will have to then go through the maf sensor which i am led to believe could cause problems with the platinum wire in the sensor.
If it is after the sensor how far up the tube do you make the connection.?
I do hope you can help.
Best regards,
tony.
