Frequently Asked Questions (FAQs)
Will disabling AFM save lifters?
Yes, if you disable the AFM, you can save lifters from failure. After disabling, the lifter will be barely used while running the vehicle, which means the lifter will have less wear and tear. Thus, you save the lifters.
Should I use an AFM disabler?
It really depends on how your vehicle reacts after connecting the AFM disabler device. If you experience some unusual problems right after plugging the device, then we would suggest you not use an AFM disabler. But if your car runs smoothly with the disabler, then you’re good to go.

Does range AFM disabler drain battery?
Sometimes we forget to unplug the disabler and leave the vehicle with it. So it’s necessary to know how much the range AFM disabler battery drain if you left it plugged in. Thankfully this device draws a minor battery life when the vehicle is in sleep mode or off. This minor draw isn’t enough to adversely drain the battery.
Some vehicles with AFM function aren’t suitable for using with the disabler, and that’s when you face the range AFM disabler problems the most. AFM disabler reduces lifter failure, stops excessive oil pump, reduces louder exhaust notes, and V8 power is always on in the disabler mode.
But the problems you may face aren’t worth it. Suppose you went to travel somewhere and due to the disabler device, your car just refused to move forward, must be a nightmare!
That’s why it’s preferable to disable the AFM lifter in another way than using a range AFM disabler. You can contact an expert and discuss with them what can be done to remove the AFM lifter completely.
