to go in the OE airbox

the K&N will need a clean i think, the Pipercross is almost brand new, only had it in for about a month when i picked up an ITG to try

K&N - £25 - £52 new online
Pipercross - £20 - £35 new online

yes the Pipercross is newer than the K&N however they are cheaper to buy, so the prices reflect this
