The NGK direct-fit oxygen sensor for BMW 325Ci (2003–2006) restores precise closed-loop oxygen monitoring so the ECU can optimize combustion, fuel economy and emissions. NTK’s sensor designs emphasize durability; the ceramic sensing element is protected by a 3-stage contaminant-resistant plasma jet and deposit-trap overcoat to reduce element poisoning and improve resistance to failure.
