KAX Catalytic Converter 674-891 Fit for 2012-2019 Accent/Soul/Rio

In this review of the KAX Catalytic Converter 674-891, the bottom line is simple: it is a budget-friendly replacement aimed at owners of specific Hyundai and Kia 1.6L models who need a straightforward emissions solution that mimics the original design. The converter's biggest selling point is its combination of emissions compliance and robust OE-style components, which keep the check engine light off while offering thicker flanges and aluminized heat shields for long-term durability. This review focuses on fitment, construction, and real owner feedback to help you decide if it suits your repair or replacement needs.

Key Features

• Direct fitment: Designed to fit 2012-2019 Accent, Soul, and Rio 1.6L and 2012-2017 Veloster 1.6L models for straightforward replacement.
• OE number match: Listed as OE Number 674-891 and 674891, which helps identify the correct unit for compatible vehicles.
• Emissions compliance: High-tech washcoat and an optimized precious metal load help reduce tailpipe emissions and keep the check engine light from illuminating.
• Built to last: Thick OE-style flanges, hangers, and brackets provide added strength and resistance to road stress and vibration.
• OE-style heat protection: Aluminized heat shields mirror original equipment design to protect the vehicle undercarriage from converter heat.

Who It's For

This catalytic converter is best for DIY mechanics and independent shops replacing a failed converter on compatible Hyundai and Kia 1.6L models who want a unit that prioritizes emissions compliance and a durable, OE-style build. It is also a fit for owners who need a cost-conscious alternative to dealer parts while keeping the vehicle road-legal.

It is not the ideal choice for customers who require a guaranteed OEM-perfect fit without any last-mile adjustments, or for those who expect included hardware like bolts and gaskets; some buyers report missing fasteners and minor alignment issues that may require additional parts or shop time.
