EPA / Federal Compliant; ECO III Catalyst
EPA / Federal Compliant Converters are not legal for sale or use in the state of California. Restrictions apply in New York and Maine.

ECO III Series converters are designed with twice the amount of Rhodium to help keep the Check Engine Light off on vehicles with high mileage, low emissions, or higher than normal emissions.

  • Proprietary NANO technology chemistry yields highly efficient loadings for lower cost and better converter efficiency.
  • Full top and bottom heat shields on most converters.
  • High flow design retains maximum engine output and maximizes catalytic efficiency.

EPA / Federal Compliant vs. C.A.R.B. Compliant

C.A.R.B. Compliant converters have very high precious metal loading, which reduces emissions output.

  • Required in California
  • Legal for all 50 States
EPA / Federal Compliant converters have typically lower precious metal loading and are generally more price conscious.
Have You Fixed the Problem That Caused Your OEM Converter to Fail?

Catalytic Converters are designed to last the life of your vehicle they do not fail on their own. It is important to fix the source of the problem before replacing your OEM converter. There are three major reasons a converter fails:

  • Spark Plug
  • Exhaust Valve

  • Leaky Cylinder Head Gasket
  • Silicone-Based Sealant
  • Improper Fuel (E85, Diesel)
