Fitted the snorkel up after I had mounted the filter bypass door (I had forgot about this), mounted the filter, looks good. Drilled a hole in my panel just above the handbrake as this is where I decided to fit the control cable knob. I figure this is only used in emergency so it is out of the way but accessible. Drilled the holes in the sub panel and firewall, fitted nylon bushes, and held along the way with C clamps, works how it should, another small job done.
