CNC Intake

You want to be a little careful about purchasing casting from China especially aluminum. They are having a lot of quality control problems in their castings industry so much so that some of the Japanese and Korean suppliers are pulling work from China. The problem centers around voids within the aluminum walls that the naked eye can't see but eventually you'll have a hole. Personally I don't care where it's made but the quality had better be good and I'm sure that the Chinese will figure it out just like the Koreans and Japanese Industries did, all I'm saying is be careful. If you're checking out one of these manifolds look for tiny pin holes on the inner and outer walls, there could be a void very close to that pinhole.
