TURBO COMPRESSOR HOUSING NOT INCLUDED! PICTURE IS JUST FOR DEMONSTRATING A STOCK TURBO HOUSING
L5P Intake Horn Anti-Surge Ring (2017–2025 Silverado/Sierra 2500HD & 3500HD)
Unlock better performance and turbo protection with the L5P Intake Horn Anti-Surge Ring — the perfect addition to your 2017–2025 Silverado or Sierra 2500/3500 with the L5P Duramax.
This ring is designed to work seamlessly with the WC Fab Open Intake Horn, which we highly recommend for all turbo configurations. By increasing airflow and eliminating restrictive factory design, this upgrade helps prevent turbo surge — a common issue that can lead to long-term damage.
The stock intake horn necks down just before the turbo, creating a low-pressure zone that reduces turbo efficiency, especially under heavy load. Installing this Anti-Surge Ring ensures smoother, more efficient airflow, maximizing turbo performance and durability.
Key Benefits:
- Prevents turbo surge and potential damage
- Increases airflow and turbo efficiency
- Eliminates factory intake restriction
- Ideal match but not limited to WC Fab Open Intake Horn
- Compatible with all turbo setups on 2017–2025 L5P Duramax
