Hello,
When replacing airfilter on '08 C14 abs, I noticed that it was installed the metallic side up.
However, in this video

(2011 c14)  the air filter was shown installed metallic side down

what's the right way?

thx

FSM says screen side up

...and welcome to the forum

If your filter has a metal mesh backing, it goes up to support the filter media against the engine suction. K&N filters like the one he installed do not have a metal mesh backing and you have to go by the slots on the side, like he did on the video.

Welcome to the forum!

thank you, it is clear now.


quite a chore to get to that filter ! (attaching pic for others who might be new to the bike)
I will get the 67$ K&N, so will follow the slots on the sides.

Since you have mentioned K and N - any with experience know if it is a direct fit on this bike?  Like exact same as oem replacement?  Thanks

BTW -
I ask, because on some bikes, the size is a little off.   

I use BMC ever since I put a K&N on my ZX-12 only to fibd it was near impossible to remove to clean it.

The K&N is a chore to remove. Make sure and use the supplied grease around the rim. They like to stick in there after a while.
