    2003 Kia Optima Replacement Engine Parts Reviews

    Awesome!
    When the product arrived as per usual I inspected it and it looked great! Just so happens I ordered the wrong part because of a miscommunication with my mechanic. So I never installed it hence the three stars because I'm unsure how easy it will actually be but from personal experience it should be cake.
