Notes
- Installing this kit on a cab and chassis might need modification.
- This system is for the 2017 - 2019 L5P Duramax with aftermarket tuning. If your truck doesn't have an aftermarket tune and can't delete specific codes, you'll get a MIL after FASS installation. Check with your calibration supplier before installation to make sure they can delete the codes. Contact us for more info.
Additional Info
- FASS Whisper Technology (FWT) reduces noise and increases fuel flow, unlike competitors who cut flow to reduce noise.
- Performance Radius Cuts (PRC) improve fuel flow, prevent air re - entry, and eddy currents. FASS is the only one with this feature.
