O2 Sensor for 2007-2013 Mazda 3 - NGK 24442

NGK 24442 O2 sensor for the 2007-2013 Mazda 3 4-cylinder 2.3L reads the oxygen left in the exhaust and sends that reading to the engine computer. This closed-loop feedback helps control the air-fuel ratio and lets the on-board diagnostic system flag fuel delivery or catalytic converter problems.

• Vibration and thermal shock testing during development, plus testing during manufacturing
• Water-resistant connectors and harness accessory hardware for easier installation
• 3-stage contaminant-resistant plasma jet and deposit trap overcoat protects the ceramic element against poisoning
• Dual-coated platinum interface and a thinner ceramic element for quick light-off and response
