Product Description

2PCS Premium Oxygen (O2) Sensor Set (Upstream + Downstream) Replacement High-Precision Sensing | Direct Fitment | 12V System

🔍 PRODUCT OVERVIEW This premium aftermarket oxygen sensor kit includes both the Upstream (Air-Fuel Ratio) and Downstream (Diagnostic) sensors. Specifically engineered to fit Corolla models from 2011 to 2013 with 1.8L L4 engines (North American built), these sensors are essential for maintaining your vehicle's fuel efficiency and emission standards. The upstream sensor monitors the air-fuel mixture to ensure optimal combustion, while the downstream sensor checks the efficiency of the catalytic converter. Replacing aging sensors can resolve common check engine lights (DTCs), improve gas mileage, and restore smooth engine performance.
