You'd have to open the air box to change filters, but I'm pretty sure it's good to go after that!
The worst threads are the oil threads especially once someone mentions Rotella T6 oil, its all downhill from there.Here we go again with another filter thread :roll: I can just see the haters coming along soon.....the old "K&N vs. BMC vs. OEM" argument.
OP....as everyone stated no need to reflash or retune your bike with just a filter change, or even a filter and slip on. Once you go past that (Headers, block off plates, velocity stacks, etc...) you should probably tune your bike for optimal efficiency/hp
I too am a K&N fan, for one I always thought it had a deeper sound then OEM (Maybe just in my head :O) and the biggest thing as everyone mentions is Reusability which is huge to me.
Also...as someone asked this is NOT an engine mod (Its maintenance) hence why nothing has to be declared to your insurance policy.
