I have seen M2 performance offer an AST elimination kit while others like Rotary performance offer an aluminum AST replacement. Is the AST really needed?? I like the idea of freeing up some under hood space but not at the expenses of frying my motor. Any comments?

thanks

get the aluminum one.

the Mazda engineers put the AST there for a reason.

 

I was thinking about getting rid of it but I thought just in case it would be good to have. Here is a link to this guy trying to fab his own. They look really good and when I get some more mod cash then I am going to look into it.
