Motorbike air filters

Are K&n and the like aftermarket filters actually any good over stock? just wondered if its worth the spend and any realworld bhp gain at all?

Yeah that's what I was wondering,whether it added bhp without any other mod like a power commander or unrestricted pipe ect

They supposed to increase airflow yet still filter out the crap as good if not better than an OEM filter,I have a dna one fitted in my zx10r but it came with the bike,im still not sure whether it's worth spending on one if your not planning on going down the full exhaust and remapping route

You can wash the stock OEM sponge ones,I washed mine about 5 times in a bath of petrol and re oiled it,it eventually broke down so I replaced it

There's two versions tefal,one for road and one for racetrack,it states youll need fuelling adjustment for the racetrack filter

Still doesn't state if the road one improved bhp over the stock filter
