Another question for you Hyundaitech
 

So you may recall my discussion rpeviously about my 2006 Sonata and an
engine whine I developed. Well they have finally agreed to replace the
part they have diagnosed as making the noise, the Variable Intake
Manifold. I made the appointment and when they called they told me my
"Surge Tank" was in, which is definitely NOT the Variable Intake. I spoke
to the Service guy who will be doing the repair and he said the Surge Tank
is part of the manifold and that it is the right part. Can you verify
this is accurate information? I am taking this in on Thursday for the
work. Thanks
