Looking for resources for A2W intercooling

Thanks for all the input guys.

ive used them a bunch of times and they can make custom size cores too. i wouldnt trust a low cost no name a2w IC because you run the risk of it leaking and thats obviously no good.
chiseled and precision are very close in comparison i would definitely buy from either of those companies.
Cheap IC cores will not have the cooling affect that a well made and designed one will.
Just my .02
