2014-2018 Chevy Silverado 1500 Engine & Performance

Every engine and performance part here is fitment-verified for the 2014-2018 Chevy Silverado 1500 with the 5.3L or 6.2L EcoTec3 V8. Coverage spans LT, LTZ, High Country, and Custom trims with S&B and aFe Power cold air intakes, DiabloSport Trinity 2 and inTune i3 tuners, headers, and cat-back exhaust.

Will a DiabloSport tuner disable Active Fuel Management? Yes. Trinity 2 and inTune i3 ship with preloaded tunes that electronically shut off AFM, sharpen throttle, and add 15-25 horsepower on a tune-only file with no check engine lights.

If it is listed here, it bolts to your EcoTec3 -- guaranteed.
