STM -AN Water Neck with 1/8" NPT - Evo 6/7/8/9

STM Tuned Inc.


Fits these Applications:
Mitsubishi Lancer Evolution 6/7/8/9
(* Not compatible with Evo 1-5 *)

The STM -AN Water Neck for the Evolution 6/7/8/9 allows you to run -AN fittings from your water neck to radiator and also includes a convenient 1/8" NPT bung welded right on top for a clean install with your water temperature sensor & gauge.

If you're running a larger exhaust manifold the factory-style coolant hoses get in the way. Installing a STM Billet, half-size or JDM radiator that moves the upper neck can eliminate that problem, and this waterneck gives you the option of making your own -AN upper radiator line.

STM Welded Water Neck

Just received my water neck the other day and am very pleased with the quality of the welds and the product itself, well worth the purchase compared to hacking the factory neck and welding a fitting on yourself. Would definitely recommend!

Thanks for the review Trevor! Glad you were satisfied, we look forward to helping you get what you need in the future.
