1998.5-2002 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 Intake Spacer Kit (WCF100338) for optimum airflow 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, and 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 fasten the oil dipstick tube securely. Connecting the Intercooler pipe to the intercooler, and Pipe to Horn, are supplied with 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 are rounded off with WCFab's high-quality powder coat finish in your color of choice.
