Review on 🔌 RA003 GM V8 V6 Engine Active Fuel Management AFM Disabler Device for Enhanced Performance by Abdirahman Elmer

If you have an Eco version An engine that switches from four to eight cylinders while driving, the eight cylinder circuitry lights up and helps prevent head damage. General Motors will not tell you this will happen to the engine. Plus, fuel economy increased by 2 mpg! Worth buying. The only downside is that the car has to be unplugged for diagnostics! Follow the instructions and disconnect the battery to install! Find the right one for your car
