Looking for the piece that fit's into the stock airbox on an 04 airbox that supposively tells you when the filter is bad. My buddy can't find his stock setup, and is switching his volant for a K&N, and i guess the K&N needs that piece for their kit. Prefer if someone in the Detroit area has one, that or close and cheap, if it's too much, i'lll have him find a plug or something.
