In 2018, 80 Walker CalCat California Air Resources Board (CARB) compliant catalytic converters will be introduced by Tenneco. The company also will continue to expand its Walker Ultra Environmental Protection Agency (EPA) compliant converters to cover millions of additional late-model passenger vehicles. The Walker replacement converters will include coverage for early, pre-OBDII applications to the latest vehicles certified to the U.S. LEV1 SULEV (super ultra-low emissions vehicle) classification. Walker CalCat converters comply with specific pre-OBDII and OBDII requirements in regions following CARB emissions standards. These units feature the right loading of precious metals, the proper catalyst material and design, and a high-technology washcoat, providing enhanced oxygen storage capacity.
