The key part is Mitsubishi optical sensor used on oem cars. Look for the 3 triangles logo inside. All others are junk. As a LT1 owner and longtime member of the ImpalaSS forum, I have three original used vented optisparks. Clean, tested, low miles.I could sell one.
Many owners have gone hundreds of thousand miles on GM originals. Great misunderstanding and unfounded criticism on this subject. Cap and rotor replacement as mentioned should be done.
