    ANGE ELEC

    ANGE ELEC AFM/DFM Disabler RA003 Active Fuel Management Delete Keep Engine V8 V6 Trucks&SUVs 4.3L 5.3L 6.0L 6.2L AG001

    • 【Protect battery & Low-Power Eye-Care LED】The circuit of AFM Disabler utilizes low-power standby technology, minimizing the device's standby power consumption. The LED bulbs emit soft light, ensuring that even during extended nighttime drives, the eye-friendly indicators prevent eye fatigue
    • ️【100% After-Sales Satisfaction】​​If you encounter any quality issues or are dissatisfied with our AFM Disabler upon receipt, you can initiate a return or exchange. Even if it's beyond the Amazon after-sales period, you can inform us of any issues through the purchase page, and we will promptly address your concerns
    • ️【Long-Term Use Reduces Fuel Consumption and Protects the Lifter】When in V4 mode, oil often splashes onto the top end of engine components, over-lubricating valve seals and being drawn into the PCV system. After driving thousands of miles with the AFM/DFM disable module, remaining in V8 mode for an extended period can prevent or reduce oil splashes on the valve guide/PCV system and potential oil ring "sticking" issues, aiding in burning off deposits. Thus, long-term use can conserve fuel and safeguard the engine's lifters. However the device may initially increase oil consumption, depending on your driving style and road conditions
