Common Problems This Part Addresses

• Check engine light caused by catalytic converter efficiency faults
• Failed emissions inspection due to converter deterioration
• Restricted exhaust flow from a worn or damaged converter

• Fitment issues from using a universal-style replacement instead of a direct-fit unit

Installation Notes

This converter uses a direct-fit, bolt-on design for easier installation with no cutting, welding, or fabrication required. Verify the vehicle’s year, model, and position before ordering, since fitment differs between Mazda Protege and Protege5 applications. Confirm oxygen sensor placement and exhaust flange alignment during installation to ensure proper sealing and sensor operation.
