If your check engine light is on for catalytic converter issues on certain Hyundai or Kia models, this A-Premium kit might be the fix. It's a 2-piece set that combines the front exhaust manifold and the catalytic converter into one replacement unit, which is how many of these cars are designed. It's a direct fit for models like the Sonata (06-07), Azera (06-10), Entourage, Kia Sedona, and Amanti with the 3.3L or 3.8L V6 engines. It's made from stainless steel and comes with the necessary gaskets and bolts. IMPORTANT: This is an EPA-compliant federal emissions part. It CANNOT be sold or installed in California, Colorado, Maine, or New York if your car is originally a CA emissions vehicle. Always check your under-hood emissions label and state laws first. A complete, quality solution for the right vehicle in the right state.
