WCF Intercooler Pipes

Market Description

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.

Associated Comments

2003-2004 Models Only - This 3.5" intake horn is significantly larger than the stock piece it is replacing. The smooth radius bends on the new part requires the plastic shroud over the throttle assembly on earlier trucks to be trimmed for proper fitment and installation.
