Are Aftermarket Three-Way Catalytic Converters Effective?

[DeCassidy]

Replacing with a quality-qualified aftermarket three-way catalytic converter is effective. Recommendation to replace at authorized locations: Without professional knowledge, it's advisable to choose an authorized 4S dealership to replace with an original three-way catalytic converter. The quality of the three-way catalytic converter directly affects whether the vehicle can pass the annual inspection. Generally, the original three-way catalytic converter has better compatibility than aftermarket ones, thus effectively catalyzing harmful substances in the exhaust. Avoid using inferior products: Using a substandard three-way catalytic converter not only causes excessive emissions but also increases the vehicle's exhaust pressure, adversely affecting the engine's power output.
