Introduction 

Many of you are already aware of the functionality of an AFM disabler. Essentially, it’s a simple little device that keeps the cylinders running at their full potential. 

In short, they are responsible for meddling with the active and dynamic fuel systems that may downgrade the cylinder’s performance at times. In addition, you are getting better exhaust sound output if you use the best AFM disabler. 

That was a quick refresher on AFM disabling devices. 

Now let’s talk about the choices for 2020. The options we have for you today should get the job done if you want the full V8 functionality at all times. 

Let’s get started.
