thats a good thing, right? superdave was having all sorts of issues with this car, was funning like a dog. Put it on the dyno and it ran low 90's, i took the airbox off and the "white thing" was no installed properly, put it back on and he ran 104kw i think. So you do need it. This part was also changed as part of the recall on the sportivos, the original one was the same as all the 1zz-fe's the new one has just a single fin running top to bottom.
