Z22SE Found this above Cylinder 4 on Intake Valve

#4
looks like a piece of an airbox or something, quite strange how it's got there
not seen anything like that on any of my 2.2's
looks like something has been dropped in the inlet manifold at some point and made its way to the head inlet port?
My previous airbox was shattered and broken, but I changed it half a year ago.. Oh god.. Piece of airbox inside there doesnt sound too good..
