Air Intake options

Atm ive got the standard 197 airbox with the k&n panel filter in, im thinking of changing the air intake and if so think im going to opt for the v6 airbox. What id like to know is do you reckon its worth it? although mininal gains would it actaully be better?
 
Sound wise would be completely different and it is very pleasing I must say.

I have been in a car with it and it does sounds very nice, plan to get this setup also.

Yes from me.
