This product is designed for vehicles equipped with a 2.5L engine and an exhaust system OE number of 674-659, applicable to 2002-2006 model years. It is an integrated assembly combining the exhaust manifold and three-way catalytic converter. The housing is made of stainless steel, with a honeycomb ceramic substrate inside coated with platinum, palladium, and rhodium catalytic materials. This structure converts carbon monoxide, hydrocarbons, and nitrogen oxides in the exhaust gas into relatively harmless substances such as carbon dioxide, water, and nitrogen, thereby reducing emission pollutants. The product is designed to match the original equipment dimensions and mounting holes, with the flange interface aligning closely with the corresponding position on the original exhaust system, allowing for straightforward alignment and installation with minimal modification. Before purchase, please verify that the actual OE number and engine displacement of your vehicle's exhaust system match this product. Prior to installation, it is recommended to check other exhaust system components for aging, corrosion, or leaks. After installation, a professional technician should confirm that all connections are properly tightened and sealed to avoid leaks that could affect normal engine operation and emissions testing results.
