Wehrli 17-19 Chevrolet 6.6L L5P Duramax 3.5in Intake Horn w/PCV Port - WCFab Grey
The Wehrli Custom Fabrication 3.5-inch Intake Horn with PCV Port in WCFab Grey is a precision-machined billet aluminum upgrade for the 2017–2019 Chevrolet L5P Duramax intake system. Replacing the factory plastic intake horn — which is prone to cracking and restricting airflow under heat and boost — this horn increases the turbocharger inlet diameter to 3.5 inches, improving air delivery for better turbo response and diesel performance. The integrated PCV port ensures factory-correct crankcase ventilation and EPA compliance.
Finished in WCFab signature Grey powder coat for a custom look. Pairs perfectly with WCFab intake pipes and cold air intake systems for a complete intake upgrade. Made in the USA by Wehrli Custom Fabrication.
Fits: 2017–2019 Chevrolet 6.6L L5P Duramax
