STM Water Neck With NPT Temp Sensor Bung | 2003-2006 Mitsubishi Lancer Evolution 8/9 (EVO-WN18NPT)
The STM 22AN Welded Water Neck for the Evolution 8/9 allows you to run a 22AN fitting from your water neck to radiator. Often running large manifolds, the factory-style coolant hoses get in the way, so running an Evo 5 radiator or half-radiator can eliminate that problem, and this water neck gives you the option of making your own coolant line.

I had previously opened my thermostat housing to add a coolant temp sensor, but that was a garbage move compared to this set up. It's put together well, and coated after the bung was welded on. Looks much better, and no leaks. Highly recommended if you are modifying your cooling system, or just adding a gauge.
