Started by enlarging hole in side of engine bay and moved fuse box forward. Covered edges of hole in rubber. Already had a 5 inch flexy duct connected to brake duct to channel air in

Moved battery forward, screwing the tray into the body

I cut one of the battery screw hooks to stop it from hitting the bonnet

I then stuck piece of rubber onto the side of the battery

Using a template, i made got a sheety to make me a divider out of 3mm aluminium. I then drilled out the hole for the afm and the screw holes, covering the edges in rubber

Screwed it together, with a new gasket between filter flange and divider, used existing o-ring between divider and afm

Finished product in the car, holds itself in there tight,i just screwed a piece of angle into the body to hold the divider in place

Pretty good height, am going to hang rubber from bonnet soon to give complete seal
