Pipercross or K&N?

I've just noticed I've got some overspray paint on my air filter which I don't think will come off.
Original Pipercross (cheaper) or 'upgrade' to K&N? Is the K&N any better or it is better to go with the Pipercross again and have £30 towards half a rank of fuel.
Thanks.
Was that a J Halfa Rank of fuel? Well bang ma gong......Original Pipercross (cheaper) or 'upgrade' to K&N? Is the K&N any better or it is better to go with the Pipercross again and have £30 towards half a rank of fuel.

Mine has a K&N, but I wouldn't say I can tell the difference.

I have recently upgraded to the K&N on mine. Apparently they are both much of a likeness when clean but the K&N will continue to flow well when it begins to get clogged up whereas the Pipercross apparently suffers more.
Sums it up 
I went for Pipercross in the end as it was the item I could get the quickest and dont do huge amounts of mileage so cleaning once a year is no issue
Thanks all for the comments.
Decided to go Pipercross in this kit from Clevor Trevor (with a TVRCC discount) to get some spares at the same time.

Another vote for K&N here, quite expensive to buy initially but it is at least a one-off purchase.
A K&N is easy to service, seems to flow well and if you look after it should last indefinitely.
My only negative experience being when the rubber collar of my K&N split, the filter element was perfectly serviceable so I made up a new collar using some cheap gutter parts from B&Q avoiding the expense of buying a complete new unit.
Pleasingly the rubber collar is now stronger than it was when new, the filter should last a lifetime with regular cleaning.
Just make sure you don't overload it with oil when you've cleaned & dried it and you'll be very happy with the K&N.
If you're taking a long term view the K&N is well worth the initial extra investment over the foam Piper-X which seems to become very dirty & clogged up after just a few hundred miles.
This means cleaning it very regularly & in my experience if you do clean the Piper-X as regularly as it demands it wont be long before the foam starts to fall apart.
Get the K&N

Inspect it if the pleats are really grubby and congested then you need link 
the trick is not allowing the dirty solution into the insides of the filter 
do they still brag about 100k between servicing/cleaning though ? 
very optimistic IMO http://www.amazon.co.uk/Cleaning-Kit-air-filter-55...

The K&N web site says this about cleaning.
4. How often do I need to clean my K&N air filter?
If you have not experienced a decrease in mileage or engine performance, chances are your filter is fine and does not yet need cleaning. To be more specific, the filter does not require cleaning if you can still see the wire screen on the entire air filter regardless of how dirty it may appear. When the screen is no longer visible some place on the filter, it is time to clean it. When used in normal paved road, street or highway conditions, our replacement air filters that fit in the factory air box should require cleaning every 50,000 miles and our large conical filters on an intake system should require cleaning every 100,000 miles. When used in dusty or off-road environments, our filters will require cleaning more often. We recommend that you visually inspect your filter once every 25,000 miles to determine if the screen is still visible.
Personally I couldn't leave mine for anything like those intervals before cleaning it. I remember reading somewhere that the filter can only be cleaned a limited no. Of times before needing replacement.
