No more frustrating transitions between V4 and V8 operation. Just smooth, consistent power whenever you need it. Designed for GM trucks, SUVs, and cars, the AFM/DFM Disabler helps eliminate issues like excessive oil consumption, lifter failure, and rough idle, giving you improved reliability and a stronger, more responsive driving experience. Fits all V6 and V8 General Motors (GM) active or dynamic fuel management vehicles, includes cars, trucks, and SUVs except 2022.5+ Refresh model trucks or 2021+ SUVs.
