Wehrli 3.5" high-flow intake horn and driver-side intercooler pipe kit for 2003–2007 5.9L Cummins. This aluminum replacement eliminates the restrictive OEM cast horn and failure-prone plastic intercooler pipe, offering a full mandrel-bent 3.5" elbow welded to a CNC-machined flange with optional 1/8" NPT ports, a threaded bung for the oil dipstick, and supplied silicone boots and stainless t‑bolt clamps for a durable bolt-on upgrade.
