This oxygen sensor is designed for Mitsubishi Lancer EX (Wing) 2009-2015 1.8L (4B10) and 2.0L (4B11) engines, also compatible with 2010-2016 ASX 2.0L, ensuring precise fit with the original exhaust system. It monitors exhaust oxygen content and feeds back to ECU to optimize air-fuel ratio, improving fuel economy and reducing emissions. OEM numbers 1588A141 and 149100-6664 for quick cross-checks. Replacement difficulty is moderate; use a professional oxygen sensor socket to avoid thread damage; apply anti-seize before installation to extend life. This high-precision signal output type offers faster response than standard sensors, suitable for bulk purchase for repair shops or fleets to reduce engine fault light issues caused by sensor failure.
