GM check engine light problems? Eastern ECO-GM Converters are designed to help keep the Check Engine Light (MIL) off on.


Developed specifically to meet the emissions challenges of GM 2.2, 3.1, 3.4, and 3.8L engines, our new ECO-GM catalyst formulation will meet these engines’ special OBDII requirements.
