304 Stainless Steel Coolant Pipe & Intake Extension Kit For Detroit 14L Series 60 Engine

If you’re working on a Detroit 14L Series 60 engine, this kit’s a lifesaver.

It includes a stainless steel coolant pipe (from water pump to oil cooler) and an intake extension pipe—both made from tough 304 stainless steel to resist heat and corrosion.

The coolant pipe stops overheating and leaks, while the intake pipe smooths airflow for better combustion.

Fits trucks like Freightliner Cascadia, Western Star 4900, and Peterbilt 379—but not 12.7L engines.

Comes with a 1-year warranty, and no need to swap the intake manifold.

Part number 23505899, new in packaging.

Keep that rig running cool!
