What Is A Mantzel Powerbox... What Does It Do..??

I do believe its a replacement inlet manifold, usually found on the corsa sport or the gsi. The inlet is restricted on these models and basically the Mantzel manifold lets it run at its full standarrd potential. Dbilas also make an inlet manifold that does basially the same thing.
