Step one - ditching the air injection system...

The kit comes with two pretty copper anodized block off plates that allow you to remove the popping deceleration from the valves allowing air into the exhaust. Also, as the intake tract will be pressurized, you wouldn't want all that boost just being diverted into the header pipes, right. The componentry also lives where the intake piping will, so away it goes.

Remove the airbox lid, the filter, push the rubber tubes in on themselves so they tuck into the frame holes. Remove the air temp probe from the right lower corner, ziptie this down so the tip rests just above the clutch cable, in as much free air as possible.

Unbolt the airbox from the baseplate, twist it out of the frame and remove. Now pull the rubber ram air tubes out. Undo the clamps holding the baseplate to the throttle tubes, unclip the air injection hose from the upper left hand side, and remove the baseplate.

Now unplug the two harness connectors to the air valve assembly, the grey gets plugged back together and simply pushed out of the way, the white other may be left unconnected, as no ecu faults will trigger.

At this point, I removed the air valve covers and reinstalled the pretty copper plates, but the manual and, in retrospect, I recommend waiting until the radiator is removed in a few steps as space to even turn the bolts is very limited. You can see here the rightmost cover is on, the left still has the stock cap with hose barb bolted on.
