Thanks Billbo, it's good to see they fit in the standard space.
Your image has also reminded me that I have a bit more height to play with than I was thinking.
My M900 came fitted with separate K&N Filters, I've since replaced the airbox, but never fitted the lid because I made up an Aluminium clamp plate to hold the filter down instead.
I was thinking that the top of the coils was about as high as I could go without touching the underside of the tank, but your image has reminded me how much higher the airbox lid is than the coils, so I should be able to mount the TCIP4 upright if I shunt the coils over to Port by modifying the bracket.
Just need some time in the garage to do it, hopefully this weekend coming.
