Sourcing a 4.4L P65 V8 engine is not the easiest task to begin with, as very few were made by BMW Motorsport.
However the S65 4.0L V8 powerplant can be used as an alternative, with great results.
The key to perfection is installing the Supersprint Tubular Headers and Race exhaust, which have been designed with the goal of extracting the most Hp from both the P65 and the S65 motors.
Handcrafted individually, these are another sample of the Supersprint work of art headers made available to the public.
