Product Details

The Fleece Performance High Flow Intake Horn is engineered to maximize airflow for 2017 and newer GM Silverado and Sierra 2500/3500 trucks equipped with the 6.6L L5P Duramax diesel engine. This performance upgrade replaces the restrictive factory intake horn with a high-flow design that improves throttle response and supports increased power output.

Key Features:

  • High-flow design eliminates factory intake restriction for improved air delivery
  • CNC-machined construction ensures precise fitment and durability
  • Direct bolt-on replacement for the stock intake horn
  • Smooth internal passages reduce turbulence and pressure drop
  • Enhanced airflow supports tuning and other performance modifications
  • Compatible with factory and aftermarket air intake systems

This intake horn is an essential upgrade for L5P Duramax owners looking to optimize airflow, whether running a stock tune or modified setup. The precision-engineered design provides a noticeable improvement in engine breathing while maintaining factory reliability. Installation is straightforward using basic hand tools and factory mounting points.

The price was the best I found. It took way too long to finally ship (in my opinion) but FedEx got it here quickly so it worked out within my time frame. Overall, I would consider them again if the price is right and I'm not under time constraints

Easy to find everything

Called to make sure it fit, ordered o line, great experience with ordering.

GREAT PRICE FOR PARTS THANKYOU!

Quick and easy. Hopefully the shipping and arrival are the same.

Fast and simple

Did not like having to fill out all of my information in order to get a shipping price.

Thanks

Smooth process and quick shipping
