Whose kept their oem air intake?
Vwgtiking:
So, oem is not very good? I thought it would be fine? And should go for an enclosed filter. What options are there for enclosed sub £200.

OEM is good. You'll really benefit from a cone filter when you're trying to improve flow, ie maxing out the turbo at Stage 2/2+ levels of tune.
But for standard boost or Stage 1, opinion is pretty divided. A few people report losing low down torque and responsiveness with a cone setup, which is a trade-off for the extra flow and therefore power you'll gain at higher revs.
I've read plenty of accounts of people going back to the standard airbox setup at Stage 2/2+ power and actually finding it nicer to drive, perhaps at the expense of a few peak horses (pub talk figures), but if it's nicer to drive that's surely a better objective.
What car is yours - K03? Remapped?
What are your long term plans for tuning, and how do you want the car to actually drive?
Vwgtiking:
I have k03 just stage 1 remap. Not sure on plans really. Just wanted a nice grunt will better flow. Or the if there is a whoosh then only come in at 4k or something so it's not noisy for town driving.

You thought about going Stage 2 with a good downpipe and sports cat/decat instead?
There's more to gain flow wise getting gas out than air in on these engines. It'll sound good, and if anything help the turbo spool a bit quicker rather than just pushing the torque curve up the revs like an intake would.
Someone in another thread went from 247bhp to 273bhp and 290 odd lb/ft to over 340 lb/ft, that's with a full Powervalve exhaust and map tweak to Stage 2 at R-Tech. And that was with a K&N panel in the standard airbox incidentally.
Yes it's a more expensive option, but maybe it'd suit what you're after more than an intake.
Vwgtiking:
Yes it's something to consider. Have been looking at k04s to.
