If your factory plastic heater inlet fitting hasn't broken yet, it's not a matter of if, but when.  It’s like Ford built a trap just to frustrate diesel owners! Swap that brittle, breakable plastic with the SPE Billet Top Adapter. Machined from aluminum and black anodized, this upgrade moves the vulnerable vent fitting safely to the side while adding substantial strength to it. It installs easily with a new O-ring and clip, ensuring your plumbing is as tough as your Powerstroke.
