OBDII By Design Technology

OBDII ENGINEERED Catalytic Converter

THREE-WAY No/Air OBDII By Design US-EPA Compliant catalytic converters are efficient at the oxidation of HC's and CO, and very AP OBDII Catalytic Converterefficient at the reduction of NOx, storing O2, and the steady release of O2 into the exhaust stream.

Designed to deal with the specific demands of today's OBDII engine operating systems and emission gas levels.


  • Larger Total Substrate Size
  • Increased Precious Metals Loading
  • Improved O2 Storage & Release
  • Lower Emissions Output
  • Long Term Reliability
