Even talking in 'stage 1' 'stage 2' is nutter comical nonscense..
Most reputable tuners highly advise a CAI from stage 2, but of course this is just utter comical nonsense on their behalf right? Albeit stage 2+ is where it's really beneficial as per my comment.
An induction kit will do very little for your engine, and also potentially damage any engine using a MAF sensor which I believe the OP's has. You may see a little increase on a rolling road result, but wait till its all warmed up inside the hot engine bay, you will actually see a decrease in power because of it.
Providing you have the CAI and map both setup correctly by someone competent enough, have the piping heat wrapped and a heat shield, then the heat soak will be minimal, so would find it hard to see that in this case (S3Alex as an example) people would see a decrease in power over the standard airbox.
Granted, you may change to a MAP sensor as you go further up the tuning ladder and running a standalone management system. the majority of standard manufacturer airboxes can provide enough airflow for over 350bhp, some closer to 500bhp, I highly doubt a 1.2 is going to get near those figures.
It does sound like you haven't actually built any engines or mapped any cars yourself and just reading off the standard internet jargon in your response.
Like I said, doing it on a 1.2 is pointless but it's up to the owner and I certainly wouldn't call him a loser for doing it.
That's true that some standard manufacturer airboxes can last to over 400bhp, however the S3's cannot. It struggles past stage 2, even the Forge Twintake and VWR closed induction kits have difficulty at stage 2+ (350bhp+) and this has been proven by -Ju- who tested & logged various kits at this stage.
You must be really clever to be able to deduct from my first comment that I am not a mechanic/tuner, even though everything that I said was true.
Chavs love induction kits as they love the 'noise' much like dump valves, along with 'dewipering' their cars its just a fashion accessory, same as atmospheric dump valves, it seems to not matter what damage and poor running performance it is doing.
I like the noise that my Revo CAI intakes makes, so that automatically makes me a chav according to your logic, others like prt57 don't like the noise but wanted the most out of stage 2+, so that makes him a loser..
I too would also not change the diverter valve on my S3 to a dump valve.
De-wipering makes the S3 look better in my opinion, it doesn't in yours, so what? I don't go around insulting people for their tastes so guess I'm intrigued why others can't do the same and be constructive instead.
