RA003 Active Fuel Management (AFM) Disabler – Plug & Play Device For GM V6/V8 Vehicles (Not For 2019+ 10-Speed)

About This Product

GM truck and car owners, do you hate the Active Fuel Management (AFM) system that shuts off cylinders to save fuel? It can cause lifter failure, oil consumption, and an annoying vibration. This RA003 AFM disabler is a simple plug-and-play fix. You just plug it into your OBD-II port (under the dash), and it tells your ECU to keep all cylinders running all the time. No programming, no cutting wires. It's compatible with a huge list of GM vehicles with V6 or V8 engines from roughly 2004 to 2018 (Chevy, GMC, Cadillac, Buick, etc. – see the full list). The idea is it provides smoother power, may improve reliability, and gives you back that consistent V8 feel. When you unplug it, everything goes back to stock. IMPORTANT: It does NOT work with 2019 and newer models with the 5.3L or 6.2L 10-speed transmission. Check your exact model and year before buying. A popular mod for GM enthusiasts!
