Not only does it look Fantastic, It increases the capacity of your Airbox by 30% and is about 5 lbs lighter giving you large performance gains in medium and high RPM's, and the Airducts are twice a large allowing even more Air into a motor that is practically strangled by the OE ducts! These are extremely light, made with a very high quality autoclave carbon fiber (unlike the cheap ones on eBay!!).
It requires no further modification and is completely interchangeable with OE Airbox.
Don't Forget the MWR Airfilter for the most airflow and best performance and the Carbon Fiber Throttle Body Bracket from EVR!
