Maximize Airflow with Fleece Performance

Unlock the hidden potential of your 2017-2019 GM 6.6L L5P Duramax engine with the Fleece Performance High Flow Intake Horn. Designed to replace the restrictive factory intake component, this high-flow upgrade significantly improves air density and flow to the turbocharger, resulting in improved throttle response and overall engine efficiency.

Key Advantages:

• Increased Airflow: Larger internal volume allows the engine to breathe more freely under load.
• Improved Performance: Enhances turbo spool-up and power delivery across the RPM range.
• Durable Construction: Built to withstand high boost pressures and under-hood temperatures.
• Direct Fitment: Engineered for 2017-2019 Silverado and Sierra 2500/3500 trucks for a hassle-free installation.

The factory intake horn is often a bottleneck in the air induction system. By smoothing out the airflow path, the Fleece Performance Intake Horn reduces turbulence and restriction, allowing your Duramax to perform at its best. This is an essential upgrade for enthusiasts looking to get more out of their truck, whether for towing, daily driving, or performance applications. Experience faster turbo response and a more responsive pedal feel.
