Upgrade the intake path on your 2017-2019 Chevrolet 6.6L L5P Duramax with the Wehrli Custom Fabrication 3.5-inch Intake Horn with integrated PCV Port in Gloss White. This precision-machined billet aluminum intake horn replaces the factory rubber/plastic elbow connecting your air intake pipe to the turbocharger inlet, providing a larger, smoother airflow path that reduces turbulence and restriction for improved turbo response and performance.
The WCF100721-GW includes an integrated PCV port to maintain proper crankcase pressure management on your L5P Duramax. The high-gloss white powder coat finish provides a clean, polished look that complements engine bay builds of all styles.
