Contact for FOB Shenzhen quote (tiered by quantity)
MOQ: 10 pcs
A compact plug-in AFM/DFM disabler for GM vehicles with V6 or V8 engines. It plugs into the OBD-II port and is designed to keep the engine running in full-cylinder mode (all cylinders active) instead of switching into Active Fuel Management (AFM) or Dynamic Fuel Management (DFM) cylinder-deactivation mode.
Highlights
- OBD-II plug and play — locate the OBD-II port, insert the device and wait for the indicator light to come on. No tools, no disassembly, no wiring.
- Keeps the engine in full-cylinder (V6 / V8) mode, so the driving feel stays consistent instead of switching between modes.
- Reversible — unplug the device to return to the vehicle's normal behavior.
- Power-saving design — the product materials describe an intelligent power-protection function that powers the device down when the engine is off; verify battery behavior on your sample.
- Compatibility chart covering a broad range of GM models and model years (approx. 2004–2022; examples include GMC Sierra 1500, Chevrolet Silverado 1500, Suburban, Tahoe, GMC Yukon, Camaro, Cadillac Escalade, Colorado and Canyon).
- Compact housing in black with a red OBD connector, supplied in a retail gift box.
Compatibility
Designed for GM vehicles equipped with V6 or V8 engines and AFM / DFM cylinder-deactivation systems, across Chevrolet, GMC, Cadillac, Buick and other GM-group brands. Always confirm the vehicle's model year and engine against the compatibility chart before ordering — compatibility is the number-one driver of returns for this product type.
Important notes for buyers
- AFM/DFM disablers change how the engine manages its cylinders. Effects on fuel consumption, vehicle warranty and local regulations or inspections vary by market and vehicle — do your own checks and describe the product accurately in your listings.
- Operating temperature range, input voltage, dimensions, weight and electronic certifications (e.g. FCC / CE / RoHS as applicable) are not stated in the source materials — ask for the datasheet and documents for your configuration.
