Cold Air Intakes - Fatal?

IMO the power increase claims are wildly optimistic. The other thing you have to be very careful of is not to over-oil the filter. It wrecks the MAF in no time at all. If you are doing it for the sound, I'm sure you'll be happy.
 
What Richard said [;)]

See if you can locate something like a CDA filter, which is a large canister with a replaceable carbon filter. These will give you the intake noise without the drawbacks of the K&N.

That said, I wouldn't bother personally.
 
I quite like the look of these, a bit of goggling found a bit more info

The image here shows the CDA filter attached to a 996

but it's not clear where the MAF is? On the Evoms and K&N intake systems you can see where the MAF fits.

The BMC CDA does look a little more DIY but then it's a good bit cheaper.

To start off it might be better just modding the std air box to cut off the resonance chamber. It's been talked about extensively in the past. Here's one of the best threads.

The MAF is what the silver ducting out of the right of the CDA fits into.

I know where it should go but you wouldn't fit the MAF in a hole in a flexible pipe like that.

It might be done as part of the fitting at the throttle body or at the filter but you don't appear to get anything like that in the kit from BMC you'd have to fabricate it yourself.
