Description

High flow, fabricated aluminum intake pipe and air box enclosure with dry filter assembly replaces the restrictive plastic factory parts on the 2020-2023 L5P Duramax for improved engine performance. Increases air flow to turbo producing improved horsepower and torque, quicker throttle response, and cooler intake temperatures by drawing cold air through the hood Ram Air duct and inner fender. All aluminum construction features large diameter 4" piping with smooth aerodynamic bends to improve intake air velocity, volume, and provide more aggressive engine and turbo sound during acceleration. The intake horn is over an inch larger than the OEM diameter and improves air flow to turbo by removing restriction found in the factory horn right before the turbo inlet.

Full assembly finished in your choice of WCFab's signature custom powder coat colors for a look as unique as your truck.

-Installs easily with basic hand tools.

-NO Tuning required, bolt on!

-Will fit on stock truck no other modifications or upgrades necessary!

Comments:
This pair really let's these L5P's breathe alot better. Intake horn is a hassle to install but worth it. Huge difference in throttle response, you can hear it sucking more into the intake and you can hear that turbo whistle alot better with the passenger window down. Excellent product!
