Hi all, New Z owner here. Recently picked up a 53 reg silver version and so far I'm pretty impressed! One thing that does currently need sorting however is the induction. See photo below - it appears to have a K&N cone filter connected to the intake by a Samco pipe, but there's nothing other than that. No heat shield, no cold air feed. The end closest to the air intake is covered so cannot directly connect a cold air feed pipe. This surely must be losing power rather than gaining anything - what's the best way to sort it so that we're either gaining a couple of horses or retaining stock power with a nice induction roar? I've seen talk of a 2006 airbox, what's this all about? Any help much appreciated!
