Intake Horn Anti-Surge Ring for Silverado 2500 3500 L5P Duramax 2017-2021

Feature:

L5P Intake Horn Anti-Surge Ring is the essential piece you need for your 2017, 2018, 2019, 2020, or 2021 Silverado / Sierra 2500 or 3500 L5P Duramax. We strongly recommend the WC Fab Open Intake Horn for your truck (regardless of which turbo you're running). With the added airflow, this Anti-Surge Ring will get you the performance you want without the potential damage that comes from a surging turbocharger.



Furthermore, the stock intake air-horn on the L5P is commonly replaced because it necks down just before the turbocharger which creates a low-pressure zone in front of the turbo. This low-pressure zone lowers turbo efficiency at "high load".

Fitment:

For 2017, 2018, 2019, 2020, or 2021 Silverado / Sierra 2500 or 3500 L5P Duramax
