The part is built to the following specification: Emission Standard: Ceramic. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 66345, 7421134828, 7421669944. Matching these numbers confirms a like-for-like replacement with no loss of function.
