I've cleaned and resold dozens of these. This is not the best or the worst one. It's average. But it's clean as a whistle because it has ben two stage medial blasted. It works freely and is complete. The bottom coolant passage plate could not be removed for cleaning because the bolts are frozen into place. This is common and happens with about 50% of the throttle bodies. This unit is priced at roughly half the price of a perfect unit.
