I honesty do not know if the 2003 and the 2009 use the exact same manifold, but later I will do a part number search to see if they differ. The video you posted does not show the end result so no idea if where he placed those screws did anything. eBay has some for $64 and around that price. May be worth it to buy one and cut it open to see where the baffle is, or swap yours with it and see if the problem goes away.https://www.youtube.com/watch?v=CIRI-K7abHw
Thanks for the link. So the 2AZ-FE and this one uses same intake?
On youtube video I saw the screw were inserted on the side of the intake but in the given link the screw was inserted in the middle of back.
My car 2003 camry LE 2.4L (2AZ-FE)
