This is a small adapter part, not a standalone performance upgrade - it is the coupler that connects AMS Performance's Garrett PowerMax turbo kit to your factory turbo inlet tubes.
why this one — You only need this if you are already running or installing the AMS PowerMax big-turbo kit - it is not something to buy on its own.
