They dont make that much/if any noise like an aftermarket induction kit.
Tbh when I had one on my cup it felt a little bit better, maybe a bit more responsive. That was with a ph1 ITG filter inside it though. It really depends where you put the cold air feed for it I guess, I took my fuel rail guard off and located the CAF to the top grill pretty much forcing the air in whilst driving... But seeing as you have aircon you may not be able to route it that way. The best thing i'd do in all fairness is get an uprated panel filter for your airbox, and save your pennies for a set of matched inlets. That will be the best £150 you can spend on the induction side of your engine! 
All induction kits just make it feel more responsive / rev more freely. Maybe a few BHP.
£150, sounds like a good medium priced induction kit. No much point in spending any more for the sake of a few BHP, save the money for the better "Power Adders"

Not quite that simple, an open cone will sound great, but will infact loose power on these cars in most cases.

Shame we cant do that airfeed on non cupped 172's
A brand new Renault filter I think would have sod all difference over an ITG, it would just need to be changed more often to retain the flow.
For £65 you cant go wrong with it tbh, its proven to be better than the standard ph2 172/182 setup, ill be able to give you a bhp/torque increase figure when i get my car back on the rollers next month. A panel filter will be around £40 new, plus the postage you have nearly bought the V6 box with a brand new standard filter in, which you can change when it gets tired.
Also from our previous RR day of 20+ RS Clios, all of the top performers bar one I think had either a V6 box or a ph1 172 box, which if you didnt know are basicly the same thing but the ph1 box has 2 small feeds and the V6 has one single 105mm daddy feed.

If you watch this shameless ASW video loud and through headphones you can hear the V6 airbox as I floor mine towards the camera a few times (best is at 1:50), I think it sounds mint.
Along with removing the power steering, fitting this improved my RR figures at Surrey RR by 10bhp...so about 3bhp from this airbox with my upper front grill CAF pickup (the same as Nick172Cup) is a good estimate. Charlie let me rotate the airbox while it was on the rollers so we did a back-to-back run with no CAF and it drawing air from behind the NS headlight for comparison, the curve was all over the place for the last 1,000 rpm. It needs a good feed.

I agree that the airbox is a very good induction setup, not disputing that as I had one myself! Though I ran a brand new standard filter and then an brand new ITG filter for it, and the ITG imho felt less restrictive and free revving, and also gave a really small induction noise. I just feel for the money you spend, for a little bit more you could get a set of matched inlets which would make a huge difference in comparison to an air filter. Seeing as the OP has a 172, he probably would see quite a difference as I know I did!
