How often should a three-way catalytic converter be cleaned?

[MacJudah]

Generally, a three-way catalytic converter should be cleaned every 20,000 to 30,000 kilometers of normal driving, but vehicle owners should adjust the cleaning frequency based on actual usage conditions. If there are issues with exhaust emissions or if the vehicle still lacks power after cleaning the fuel injectors and throttle body, it may indicate a clogged three-way catalytic converter, requiring prompt inspection and cleaning. The three-way catalytic converter is an essential external purification device installed in the vehicle's exhaust system. It converts harmful gases such as CO, HC, and NOx from vehicle exhaust into harmless carbon dioxide, water, and nitrogen through oxidation and reduction reactions. Known for its stable performance, reliable quality, and long lifespan, this product is widely compatible with models from Toyota, Honda, Buick, Audi, Volkswagen, Hyundai, Suzuki, Changhe, and more.
