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.
