If you still want a power mod, then get headers .Absolute BEST bang for the buck you can get for M54.

However , if he just got the car it would make MUCH more sense to get him a new cooling system and new FCAB.

PS. M54 is not hopeless powerwise ,lol. M54 is much more capable then any of its M5x predecessors.
