i search the web before tackling mine and mount nothing on the MKII..
this is to detail taking the vent out and install the pod ring.. i do not currently have a boost gauge to do a full gauge write up but will add to this once i do so..
first is to get a decent screw driver to pry out the vent.. just stick the screw driver between the vent and dash and wedge slightly til you can get a finger grip on it and use your hand to pull the rest out..
2nd step is to stick a think screw driver between the metal trim and plastic for the vent and give it a slight twist i tried 2 diffrent spots and it popped off.. just repeat going round the trim till it is completly off..
the end result will look like this..
next step is to remove the plastic trim piece that opens and closes the vent from the metal trim ring.. look on the inside and you will see 3 tabs.. you can use you flat screw driver and pop them loose then seperate..
you will end up with 2 pieces like this..
next line up the 3 tabs from the OSIR pod it will only go on 1 way as the tabs are not evenly spaced.. so if you put it on you will have to spin it until the tabs line up then click it in place..
final result with out gauge installed is this..
i hope this helps i few people out.. im far from a teacher.. and not use to doing step by step write ups..
