Have a pair of original Prova brake ducts (in carbon fiber) for sale. These came off my 2007 STI and I'm not sure about compatibility with WRX control arms or the newer models.
Condition is good except for a small crack on the mounting tab of the LHS duct (see 3rd pic). Nothing structural, and should be an easy fix to glue or reinforce it back in shape.
Asking $185 shipped. Can't (or don't want to) remember what I originally paid for these as they're out of production, but safe to say easily close to double what I'm asking, I believe. PM me if interested.
