JB3 is just like the factory power curve only a lot steeper !

The K&N replaces the factory airbox completely and besides allowing the engine to breathe better at the higher boost levels you can hear the turbos spooling up more which is rather nice in itself ! 8-15 rwhp is claimed in conjuction with JB3.
