STM Evo 6/7/8/9 Modified Water Neck *Discontinued*

No Longer Available:
STM now offers these: STM Billet Water Neck for Evo 6/7/8/9

Discontinued:
The STM modified OEM water necks for the Evo 6/7/8/9 is available with a convenient 1/8" NPT bung welded right on top for a clean install for your water temperature sensor and gauge. Also available with the -AN bung option to connect -10AN, -12AN or -16AN lines and fittings to your upper radiator outlet.

If you're running a larger exhaust manifold, the factory-style coolant hoses get in the way. Installing a half-size or JDM radiator that moves the upper neck to the right of the engine bay can eliminate that problem!

Vehicle Fitment:
Mitsubishi Evolution 6/7/8/9
• Not compatible with Evo 1-5
