2014-2018 GMC Sierra 1500 Engine & Performance

Every engine and performance part here is fitment-verified for the 2014-2018 GMC Sierra 1500 with the 4.3L V6, 5.3L V8, or 6.2L EcoTec3 V8. Stocked: S&B and aFe POWER cold air intakes, Edge Products tuners and digital gauge monitors, throttle response controllers, and high-flow drop-in filters.

Will a tuner disable Active Fuel Management V4 mode? Yes -- the Edge Products tuners in this collection permanently kill AFM cylinder deactivation, eliminating the V4 drone and the lifter failures that plague these K2 trucks.

If it is listed here, it bolts to your Sierra -- guaranteed.
