电装3018 W16EP-U 镍合金火花塞，实惠耐用日常驾驶理想搭档

If your Toyota Camry experiences idle instability, abnormal fuel consumption, or check engine light (code related to lean/rich air-fuel ratio), the upstream oxygen sensor has aged or failed. It monitors air-fuel ratio in real time and feeds ECU to precisely control injection, ensuring efficient combustion and reduced emissions. OEM numbers: 8946706150 (also compatible with 8946733170, 8946758030); fits 2007-2011 Camry (2.0L/2.4L) and some Lexuses ES models. Installation requires a dedicated socket to avoid cross-threading; clean exhaust interface before installing; ensure wiring harness avoids contact with hot components.
