Looking for the spark plug wire separator that clips (snaps) on the side of the intake manifold. It's not part #22472KA040 (which I already ordered and returned). These clips are gray and snap into the side of the manifold. Seems as if they get brittle and dry out and break over time. Looked at Subaruparts.com and I can seem to find the correct part #!. Anyone have the correct part number?
