Which years of the Sienna will the TRD supercharger fit?

Fits 99-03 for sure, 98 as well i'm pretty sure.

Now that Toyota moved away from the 3.0L that was also used in their passenger cars, and went to a 3.3L, I don't know if the 2004+ siennas will have a TRD supercharger that fits in em. I doubt they'll make a supercharger specifically for the sienna. Too bad they didn't just go 3.4L... then you could use one of the SC's for the tundra or tacomas...
