Hyundai Repair: air box, double overhead cam, cool air intake

Question
I have a 2000 Hyundai Accent GL. I need to get my car smogged, but i have a cool air intake on it and i have no idea where the original air box is. Would the air box from a duel over cam Hyundai engine fit into my car (being a single over cam)??? Also are the O2 (oxygen) sensors the same?  Thanx

Answer
The top of the air box for the double overhead cam will be different because the double cam has not air flow sensor.  The bottom of the air box air box intake duct should be the same.

Both engines use the same oxygen sensors.

All of the above assumes we're talking only about 2000-2005 Accents.
