PN · NM23392
NM23392 is a valve spring heat insulator, part of the valve gear on the top end of the engine. The catalog note tells us it's not fitted on the inlet side of the RH1 cylinder head, which means this one has a specific application within a set rather than being a one-size-fits-all piece.
