$100, includes ups ground shipping to the 48.
this filter's ID is 43mm. from my research it should fit the ecotrons TB.
includes 2 worm clamps. will not include the crankcase breather - i did get that to work.
i did tear the mounting flange in an attempt to fit. 2 tears each flange 180 degrees from each other. see photos below.
