Wehrli Custom Fabrication WCF100528-RED 3.5" High Flow Intake Horn & Intercooler Pipe Kit - WCFab Red

The Wehrli Custom Fabrication WCF100528-RED is a high-flow 3.5" intake horn and driver side intercooler pipe kit designed for 2003-2007 Dodge Ram 2500/3500 trucks equipped with the 5.9L Cummins diesel engine. This performance upgrade kit replaces the failure-prone 3" plastic OEM intercooler pipe with a heavy-duty 14-gauge aluminum intercooler pipe and replaces the restrictive OEM cast intake horn with a full mandrel bent 3.5" elbow. The 3.5" elbow is welded to a CNC machined aluminum mounting flange with new hardware included, which perfectly matches the WCFAB Intake Spacer Kit for optimum airflow into the cylinder head.

Key Features:

• Two optional 1/8" NPT ports for boost pressure reading or water methanol injection
• CNC machined flange with 8mm threaded port to accept wire harness isolation clamp and incorporated threaded bung to fasten oil dipstick tube securely
• Mounting points to retain factory oil dipstick location and wire harness routing
• Will fit on stock truck with no other modifications or upgrades necessary
• Includes high-quality 5-ply silicone boots and stainless steel t-bolt clamps
• Finished in durable WCFab Red two-stage powder coating

The horn can be used with the OEM grid heater or other brand high-flow intake plates. Note for 2003-2004 models: This 3.5" intake horn is significantly larger than the stock piece, and the smooth radius bends require the plastic shroud over the throttle assembly on earlier trucks to be trimmed for proper fitment and installation. This kit is proudly made in the USA and is not CARB legal for sale in California.
