    Catalytic Converter

    The Catalytic Converter (BM91323H) reduces harmful emissions and restores clean exhaust flow. Porza catalytic converters provide high durability and efficient pollutant conversion.  

    FAQ

    A catalytic converter is an exhaust system component that reduces harmful emissions from the engine. Its function is to convert toxic gases such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx) into less harmful substances like carbon dioxide (CO₂), water vapor, and nitrogen.

    Key specifications include substrate type (ceramic or metallic), catalyst coating, inlet and outlet diameter, emission standard compliance, and compatibility with the vehicle. It must withstand high temperatures and ensure proper exhaust flow.

    Replacement is necessary when the converter is clogged, damaged, or no longer effective. Common symptoms include reduced engine performance, increased fuel consumption, rattling noise, or emission warning lights.

    Porza offers a fit guarantee option where your vehicle details are checked against product specifications to ensure correct compatibility and emission compliance.

    Porza provides high-quality exhaust components with fast delivery across Europe and options for online ordering or in-store pickup.

    If the fit guarantee is selected, compatibility is verified before shipping. If the product does not fit, it can be returned according to the return policy.
