Give Your New Cummins Wider Pipes And Boots That Stay Put Under Boost

On a truck that tows heavy or gets pushed hard, a small weak point in the charge air system can turn into a big problem. Wehrli points to two of them in the factory design, the angled boots and the plastic driver side intercooler pipe, and says both can lead to boost leaks or complete failures when the truck is working hard. The Stage 1 High Flow Bundle Kit replaces those parts on your 2025-2026 Ram 2500 or 3500 with heavy duty aluminum pipes that are 3.5 inches in diameter. That is a noticeable step up from the factory 2.75 inch hot side and 3.25 inch cold side pipes, which Wehrli describes as poor flowing. According to Wehrli, the wider path improves airflow between the turbo and the engine, which helps efficiency, throttle response, and turbo spool up. The kit also comes with upgraded silicone straight boots that Wehrli says handle more pressure and heat than the OEM parts, so a blown boot becomes a lot less likely. You can even choose your own powder coat color, which gives the engine bay a look that is as unique as your truck. It installs with basic hand tools and works on a stock truck with no tuning required, so you can do the job in your own garage and feel the difference on the very next drive.

Fourteen Gauge Aluminum Tubing With Smooth Mandrel Bends And Straight Silicone Boots

The Wehrli WCF100874 is a Stage 1 high flow intake bundle kit for 2025-2026 Ram 2500 and 3500 trucks with the 6.7L Cummins. It replaces the factory 2.75 inch hot side pipe and the factory 3.25 inch cold side pipe with pipes that are 3.5 inches in diameter. Wehrli makes them in the USA from heavy duty 14 gauge aluminum tube, and the smooth, aerodynamic mandrel bends are intended to add durability and optimize flow. The kit includes upgraded, high quality silicone straight boots in place of the angled factory boots. Wehrli says these boots withstand higher pressure and temperatures than OEM parts, which increases reliability and eliminates blown factory boots. The aluminum cold side pipe also takes the place of the factory plastic driver side intercooler pipe. The full assembly is finished in your choice of WCFab's signature custom powder coat colors. Installation needs only basic hand tools, and Wehrli says the kit is compatible with stock trucks and requires no tuning.
