The part is built to the following specification: Height [mm]: 283 mm, Inner Diameter [mm]: 63 mm, Outer Diameter [mm]: 93 mm, for article number: C 14 179/1, Filter type: Stainless Steel. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 1 457 433 665, 1534762, 190 9129, 1909129 and 75 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
