Why Choose Non-AFM Engines?

Active Fuel Management (AFM) technology, designed to improve fuel economy by deactivating half of the engine’s cylinders under light-load conditions, has been a notable feature in GM’s V8 engines. However, while the intent behind AFM is laudable, real-world experiences have highlighted several drawbacks. Many users report that AFM-related components are often the root cause of engine failures, leading to costly repairs and downtime.

Here are the key reasons why a non-AFM engine might be the better choice for you:

Enhanced Reliability

  • Simpler Mechanism: By eliminating the cylinder deactivation mechanism, non-AFM engines have fewer components that can fail. This simplicity translates to greater overall reliability and longevity.
  • Reduced Maintenance: Without the need to maintain the complex AFM system, owners can enjoy lower maintenance costs and less frequent repairs.

Consistent Performance

  • Full Power Always: Non-AFM engines run all cylinders all the time, ensuring that you always have the full power and torque available, without the transition lag associated with switching between modes.
  • Smooth Operation: Eliminating AFM avoids the potential issues of rough transitions and uneven engine performance, providing a smoother driving experience.

Peace of Mind

  • Less Worry: With non-AFM engines, there’s no need to worry about AFM-related issues like lifter failures, oil consumption problems, or valve train issues that have been reported by many AFM engine users.
  • Greater Confidence: Knowing that your engine is built for straightforward, reliable performance allows for greater confidence whether you’re using your vehicle for daily driving, towing, or heavy-duty tasks.
