I have a 2012 MCS and the oil catch can does not fit by the firewall any other suggestions. Do I have to change the stock intake to fit it?

 

I havce an 08, so it might be different, but on the firewall to the right rear of the engine there is a tab. Mine has a push button-type switch there. That is the typical mounting place. I'm doing mine this weekend and have scoped it out, removing the switch and replacing the screw that holds the switch holder in place with a little bit larger screw on that tab. I'll mount the OCC on the bottom side of that tab so as not to interfer with the level of the push button as it sits on top of the tab. Sorry I don't have a picture.
