2017-2019 L5P Duramax Passenger Side 3.5in Intercooler Pipe Grape Frost

Improve boost flow and eliminate restrictive factory piping with the WEHRLI CUSTOM FAB WCF100530 PASSENGER SIDE 3.5IN INTERCOOLER PIPE for the 2017-2019 GM 6.6L L5P Duramax. Designed to replace the restrictive OEM passenger side charge pipe, this performance upgrade increases airflow capacity and improves turbocharger efficiency for both stock and modified trucks. Manufactured by Wehrli Custom Fabrication, this intercooler pipe features precision mandrel-bent aluminum construction and increased diameter for improved airflow between the turbocharger and intercooler system. The larger 3.5-inch design reduces pressure drop, supports higher boost levels, and enhances overall engine performance while maintaining OEM-style fitment.
