L5P Intake Horn Anti-Surge Ring
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".

Aftermarket intake air horns have a larger inside diameter compared to stock. This helps to keep the turbo inlet well fed. Keeping the turbo well-fed is extremely important when using our Stealth 64 and Stealth 67G2 turbos where the factory air-horns anti-surge ring (2.4 inches) literally chokes the inlet of the Stealth (2.65 inches). To protect against surge and give the best flow possible we've designed anti-surge rings matched to the compressor inlet for use with an aftermarket open style intake air-horn. The L5P Intake Horn Anti-Surge Ring is essential for your performance built 2017, 2018, 2019, 2020, or 2021 Silverado / Sierra 2500 or 3500 L5P Duramax. These kits include new studs, O-ring, and nuts needed for installation.
