Anybody know if somebody makes an aftermarket steel or aluminum waterneck for the S5 cars? I hate the plastic ones and flat out don't trust them after the constant abuse and heating/cooling... I know that over the years they turn brown and become very brittle. The S4 uses a metal one, so why did mazda go to plastic? Any reason on this?



If I can't find a metal one, i'll be making one....

umm Apex13b on here made one or two not that long ago on a lathe, they looked like nice pieces, might try pming him or he might look here.



and yes i hate the plastic neck too...and its $50 from the dealer, give or take some.

Do the S4 necks bolt onto the S5?

Nope... not at all. Different bolt pattern and all.





I'll probably make one...see how it turns out,lol..

i wonder how hard it would be to redo an s4 neck, so it fits an s5. hmmm [goes to look at em in the back]

be tough. the s5 is a smaller diameter and the bolt holes are in bulges that stick out

Yea, way ahead of you on that one, lol.. I have an extra s4 and I was like...maybe just cutting/welding a new flange would work...no, not the case, lol.. that would be nice though.



I just don't know why mazda got away from the metal, maybe cost..who knows.

too bad he wont make a run of them, he has one for me, I just need to get it from him https://www.nopistons.com/forums/pub...IR#>/bigok.gif

you could just run the whole s4 water pump assembly if you have a spare one.



then with the s4 pump you can use the s4 neck.
