This product is designed for vehicles equipped with a 3.5L engine and an exhaust system OE number of 16221, applicable to 2003-2007 model years. It is a complete set of three-way catalytic converter components, typically including multiple catalytic units corresponding to different exhaust branches of the vehicle's exhaust system. The housing is made of heat-resistant stainless steel, with a honeycomb ceramic substrate inside coated with catalytic material, capable of converting carbon monoxide, hydrocarbons, and nitrogen oxides in engine exhaust to reduce the concentration of harmful emissions. Each component in the set is designed according to the layout of the original exhaust system, with flange dimensions and bolt hole positions generally corresponding to the original equipment locations, facilitating a full set replacement. Please verify that the actual OE number of your vehicle's exhaust system matches before purchase, to avoid installation mismatch due to structural differences. Since the exhaust system structure of this type of vehicle is relatively complex, it is recommended to consult the original service manual to confirm pipe routing and connection sequence during installation, and have the work performed by an experienced technician. After installation, check all connections for sealing and confirm there is no abnormal noise or leakage before regular use.
