Suzuki Oxygen Sensor 18213-65D10/65D30/65D31 234-4084 High-Temperature Resistant Ceramic Core Design

This oxygen sensor is designed for 2005-2010 Suzuki Swift 1.3L/1.5L, 2006-2011 Suzuki SX4 Sedan 1.6L, and 2007-2012 Suzuki Jimny 1.3L; precisely matches displacement requirements. Core function is real-time monitoring of exhaust oxygen content and feeding signals to the ECU to optimize the air–fuel ratio, ensuring efficient combustion and reduced emissions. OEM numbers include 18213-65D10, 18213-65D30, 18213-65D31, and 234-4084; cross-check with original parts. Replacement difficulty medium; use a dedicated socket; clean threads and apply anti-seize before installation to avoid damaging the ceramic core. Uses high-temperature ceramic core design, more heat-shock resistant than standard sensors, suitable for frequent stop-and-go or high-load conditions; helps extend service life and reduce repair rates.
