Yup---sorry, we run mostly in salt down here----Tampa Florida .....

They don't protect against salt problems. They do offer protection from galvanic corrosion that takes place anywhere in water with dissimilar metals. Most engines have them in coolers and heat exchangers. They would be a good thing to add in any engine where different metals are present. Iron, copper, brass and aluminum all inter act and will corrode when covered in water.
