WC Fab L5P Open Style Turbo Intake Horn 2020-2025
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.
This Open Style Intake Horn has been tested and proven to allow your turbocharger to get the highest horsepower possible. Don't leave power on the table, this is the intake horn you need!

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.
