heres my story.

K&N - After a bit of usage i started getting poor fuel consumption - up to 100kms less than usual. so I put on my pod then changed to my stock filter and back up to 500km per tank. both pod and stockie increased my consumpton - which imo, is better than alittle bit of extra performance which is hardly noticable anyway.

not to mention the fact u have to clean it. i just cbfed. now its for sale.
