I am trying to replace the throttle body on my 2004 Nissan Sentra 1.8. The replacement part I bought from the Nissan dealership that came in, the air intake hose is a different diameter than the original that is on the car, only one end is the right size, the end that attaches to the air cleaner. The dealership swears it is the right part. What do I do now, they just said to try it again with no other suggestions. Is there any way this part will work or are they wrong about this being the correct part?
