Ah, the 6.7L Powerstroke's infamous heater inlet tube – a true masterpiece of "it's not if it leaks, but when." That thin-walled steel line connecting to your thermostat crossover manifold just isn't ready for the long haul. It's a delightful cocktail of metal that just loves to corrode and an o-ring/tube design that was seemingly engineered by someone who clearly had other plans for the afternoon.
 
But fear not, puddle-sufferers! With the SPE Heater Inlet Tube Fitting Kit, we’ve told that problematic part to pack its bags. 

Check It Out!: https://www.spemotorsport.com/collections/powerstroke-cooling-system/products/spe-coolant-tube-fitting-kit-fits-6-7l-powerstroke

Features:
•  Easy install — Simple instructions that even an amateur can follow. 
•  Durable — made out 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 valley of the engine. Fitting converts over to a ¾” hose outlet.
