Mazda 626 Catalytic Converter 4 (Iv) (1991-1997)

The catalytic converter for the Mazda 626 4th generation (1991-2002), also known as 626 IV or GE series, is an exhaust system component designed to reduce harmful emissions. It is engineered to fit directly on specific engine models like the 2.0L (FS) and meets various Euro emission standards from Euro 2 to Euro 4 depending on model year and market.

These catalytic converters fit several Mazda 626 4th generation engines and model years:

• 2000-2002 Mazda 626 2.0L engines with direct-fit converters (compatible with OE part FS1N-20-500)
• Models from 1991 to 2002 with engines including FE(16V), FP, FS, and B69
• 1997-2003 Mazda 626 2.0i 16V with references like FAO MA6017

Each catalytic converter is designed to meet the specific emission standards (Euro 2, Euro 3, Euro 4) relevant for its engine and market.

Typical features of Mazda 626 4th generation catalytic converters include:

• Length ranges between 220 mm and 1900 mm, with common sizes like 665 mm and 1780 mm
• Weight ranges from approximately 2.05 kg to 7 kg
• Emission standards compliance include Euro 1 up to Euro 5, and designations like D3 and D4
• Constructed with high-quality materials and designed for direct fitment with OEM quality

These converters feature a durable honeycomb monolith treated with rare metals to optimize catalytic efficiency and heat resistance.

High-quality catalytic converters for the Mazda 626 4th generation are widely available from reputable brands specializing in direct-fit, EPA and CARB-compliant converters. It is important to select converters that:

• Match your vehicle’s engine model and emission requirements
• Meet EPA and/or California CARB standards for legal and environmental compliance
• Are designed for direct replacement to fit without exhaust modifications

Always check vehicle-specific compatibility before purchase to ensure legal compliance and optimal fit.

Signs that your catalytic converter may require replacement include:

• Check engine light or error codes related to emissions
• Noticeable decrease in engine performance or acceleration
• Unusual exhaust odors or increased emissions
• Visible damage such as discoloration or cracks on the catalytic converter

Perform an exhaust leak and pressure test to check for blockages or damage. A backpressure greater than 5 psi is often a sign the converter needs inspection or replacement.

When installing a replacement catalytic converter on your Mazda 626, remember to:

• Confirm the converter matches your vehicle’s engine and emission specifications (EPA or CARB compliant)
• Replace oxygen sensors if recommended, especially after 80,000 to 100,000 miles
• Use appropriate gaskets, hangers, hardware, and copper connectors for leak-free installation
• Ensure all exhaust system components fit properly and that the exhaust flow direction matches the converter’s flow arrow
• Avoid using improper fuels like diesel or E85 in gasoline engines that require catalytic converters designed for unleaded petrol

Professional installation is recommended to meet legal requirements and maintain vehicle performance.

Brand-new catalytic converters typically come with a 3-year warranty, limited to use not exceeding 100,000 kilometers. The warranty covers defects in manufacturing but requires:

• Proper professional installation and adherence to manufacturer guidelines
• Replacement of all related gaskets, sensors, and parts at the time of installation
• Use of the vehicle primarily with unleaded petrol and compliance with emission regulations

Returns are generally accepted within 30 days if the part is unused, undamaged, and in original packaging. Check specific vendor policies for precise terms. Returns of manufactured-to-order items and used catalytic converters are typically not accepted.
