There are 2 flexible pipes from the air filter housing/box to the air intake piece behind the grill.
These pipes just simply pull out.
The pieces immediately behind the grill are held in by a couple of screws. the RH side is easy to remove - the LH side is trapped by a pipe (cooling I think), there's a screw which holds that secure, if you remove the screw the pipe flexes and you can remove the front portion of the air intake.
