This is an excellent option on a new manifold to protect your investment ! PLUS….can be done to most ‘used’ Kinsler manifolds to save your investment !!!
Magnesium can corrode very rapidly when exposed to water.
This manifold corroded unusually quick; it was in the field for about two years.
There are only two threads left where the water port fitting was.
Steel ions accelerate the corrosion, so use anodized aluminum fittings on magnesium manifolds.
Using distilled water for coolant is supposed to reduce the corrosion significantly.
