Fixes the problematic OEM heater inlet tube, which is prone to corrosion and leaking at the thermostat crossover manifold.


  • Easy install— Simple instructions that even an amateur can follow. 
  • Durable— made of billet aluminum with the correctly sized o-ring rather than the factory thin-wall steel with a poorly fitted o-ring. 
  • Cleans Up Engine Valley— Great for highly modified trucks looking to clean up the engine’s valley. Fitting converts over to a ¾” hose outlet.

Vehicle Compatibility:

  • 2011-2019 Ford SuperDuty F-250/F-350/F-450/F-550 6.7L Powerstroke

The 6.7L Powerstroke has a thin-wall steel line running from the coolant/thermostat crossover manifold to the heater hose. It’s not uncommon to see coolant weeping there, specifically where the heater inlet tube meets the crossover manifold. This is due to both the metal properties, making it prone to corrosion, and the poorly fitted o-ring and tube design. Additionally, anytime there’s EGR work, turbo work, or any other movement of the tube, leaking is more prevalent. This is mostly in part to the flawed design of the tube. With the SPE Heater Inlet Tube Fitting Kit, we have resolved this issue.

This kit includes:

  • SPE designed billet aluminum fitting
  • Silicone hose
  • O-Ring
  • Hose Clamps (2)
  • Hardware
  • Installation Instructions
