i dont know why TB spacers are sold for our cars....with the IM runner length as long as it is, tq is already about as good as it can get down low (longer runners = low end tq).

k&n panel filter ($50) plus a $400 tune is about as good as it gets. TB is useful if you want some more throttle response.
