Upgrade Just The Side That Needs It

Not every build needs a full charge pipe kit, and if your hot side is already covered or you're working through an upgrade in stages, the aFe Power BladeRunner Cold Side Pipe lets you address the cold side on its own. This TIG-welded 3.5 inch aluminum pipe directly replaces the factory cold side charge pipe on your 2025-2026 Ram 2500 or 3500 6.7L Cummins, smoothing out the path between the intercooler and the intake. The mandrel-bent construction reduces turbulence and minimizes pressure loss, contributing to the smoother, more efficient airflow that supports better throttle response and reduced operating temperatures. A built-in 1/8 inch NPT port gives you a clean, factory-style location for adding a boost sensor or water methanol injection down the road, without drilling or tapping anything yourself. The pipe is finished in a wrinkle black powder coat for heat and corrosion resistance, with a laser-etched aFe logo for a custom look under the hood. Whether you're building out your charge air system piece by piece or just need to replace this specific pipe, this is a straightforward, direct-fit upgrade.

Precision Aluminum Construction Built For Reduced Turbulence

The aFe Power 46-20819-B BladeRunner Cold Charge Pipe is engineered specifically for 2025-2026 Ram 2500 and 3500 trucks equipped with the 6.7L Cummins engine. This single pipe measures 3.5 inches in diameter and is TIG-welded from mandrel-bent aluminum to maintain smooth internal transitions that minimize turbulence and pressure loss through the cold side of the charge air system. According to aFe, this design delivers a 3% airflow gain over the factory cold side pipe. Installation hardware includes premium stainless steel, spring-loaded T-bolt clamps paired with heavy-duty, 5-ply polyester-reinforced silicone couplings for a durable, long-term seal. A built-in 1/8 inch NPT port is provided on the pipe for connecting a sensor or water methanol injection system without additional fabrication. The pipe is finished in a wrinkle black powder coat for added heat and corrosion resistance, finished with a laser-etched aFe POWER logo. This product is not currently CARB exempt and is not available for purchase in California or for use on any vehicle registered with the California DMV.
