Key Features

• Vehicle Fitment: Designed specifically for Captiva Sport 2012-2015, Chevy Equinox 2010-2014 and GMC Terrain 2010-2014 with the 2.4L L4, reducing the need for adapters or custom work.

• EPA Certification: Built to meet federal emission standards, so it legally replaces a failed converter in states that accept EPA parts and maintains emissions performance.
• Materials and Construction: Stainless steel body and porous ceramic substrate with platinum, rhodium and palladium coatings enhance catalytic conversion efficiency and durability.
• Installation: Intended for bolt-on installation to manifold and downstream pipe; using specified torque on fasteners helps ensure a leak-free connection.
• Performance Focus: Noble metal loading on the ceramic substrate boosts purification capacity to keep exhaust emissions within federal limits.

Who It's For

This catalytic converter is best for car owners and independent shops replacing failed converters on the listed vehicles with the 2.4L L4 engine who need a part built to OEM form and EPA standards. It is suitable when you want a direct-fit unit that minimizes fabrication and aligns with federal emissions requirements.

It is not for owners in states that require CARB-approved parts, including California, Colorado, New York and Maine, or for anyone needing a part for non-listed vehicles or different engine types. If CARB compliance is required, look for a certified aftermarket converter approved for those states.
