The part is built to the following specification: Width [mm]: 23 mm, Weight [kg]: 0, 097 kg, Material: 55, Inner Diameter [mm]: Fibreglass mm, Outer Diameter [mm]: 69 mm. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with MERCEDES-BENZ vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 001-30-14167, 02.19.181, 03-40509-SX, 03.80184 and 59 more. Matching these numbers confirms a like-for-like replacement with no loss of function.
