Description

Part #: WCF100528-GM

2003-2007 5.9L Cummins High Flow 3.5" Intake Horn and Driver Side Intercooler Pipe Kit. Kit replaces the failure prone 3" plastic OEM intercooler pipe with a 3.5" heavy duty 14g Aluminum intercooler pipe and the OEM cast intake horn, which is necked down to less than 1.5" wide, with a full mandrel bent 3.5" elbow. The 3.5" elbow is welded to a CNC machined aluminum mounting flange (new hardware included) which perfectly matches the WCFAB Grid Intake spacer kit for optimum air flow into the cylinder head. Our horn can be used with the OEM grid heater or other brand high flow intake plates however the internal surfaces may not be as perfect of a match as our Billet Intake Spacer Kit offers. The CNC machined flange has two incorporated 1/8" pipe thread ports for boost reference or other injectables, as well as an 8mm threaded port to accept the wire harness isolation clamp to support the OEM wire harness. The 3.5" High Flow Horn also has an incorporated threaded bung to securely fasten the oil dipstick tube. Connecting the Intercooler pipe to the intercooler, and Pipe to Horn, are supplied high quality 5 ply silicone boots and stainless steel t-bolt clamps. No need to reuse any worn out or torn OEM boots or clamps. The Intake horn and Intercooler Pipe is rounded off with WCFab's high quality powder coat finish. Replaces the following MOPAR part numbers: 52028895AE, 52028895AC, 52028895AD, 5086828AA.

MIA's Description

This kit replaces the restrictive 3" plastic OEM intercooler pipe with a 3.5" heavy-duty 14g Aluminum intercooler pipe and the OEM cast intake horn with a full mandrel-bent 3.5" elbow. The CNC machined aluminum mounting flange ensures optimal airflow and includes two 1/8" pipe thread ports for boost reference or other injectables. The kit also features a threaded bung for secure oil dipstick tube fastening and an 8mm threaded port for wire harness isolation. High-quality 5-ply silicone boots and stainless steel t-bolt clamps are included for a secure connection. Finished with WCFab's high-quality powder coat in your color of choice, this kit offers 60% greater flow than stock for significant power gains. Installation on 2003-2004 models may require trimming of the plastic shroud over the throttle assembly.
