Wehrli Stage 1 High Flow Intake Bundle Kit

2019–2024 Ram 2500 / 3500 6.7L Diesel

Part #: WCF100292-GRY

Overview

The Wehrli Stage 1 High Flow Intake Bundle Kit is engineered specifically for 2019 to 2024 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine. This kit replaces the restrictive factory intercooler pipes with larger diameter 3.5" pipes designed to improve airflow and reduce turbo lag. Ideal for diesel enthusiasts seeking enhanced throttle response and increased reliability, this upgrade addresses common issues found in the stock piping such as crushed or undersized tubes that limit performance.

Designed to withstand the demanding conditions of heavy-duty diesel applications, the kit includes premium silicone boots that offer superior pressure and temperature resistance compared to factory components. This ensures a more durable and leak-free connection, eliminating the risk of blown boots under boost.
