OK so I have had the Carbinio CAI on my 2007 Rabbit (with the MAF installed correctly) for almost 8 months and now when it gets cold i throw a cel and the dealer said it is because the temp. sensor the 90 degree angle sensor everyone is talking about is not on the intake AND IT HAS TO BE IF YOU HAVE AN INTAKE.
I now need to either drill into the side of the carbon fiber intake or get a totally new one.
I also need to buy a new Mass Air Flow Sensor (MAF) because running with my proportions off of air to fuel has caused the sensor to get messed up.
SO either get a BSH or be prepared to drill into the CAI if you have the 2006-2007(maybe 2008) designed motor.
The newer design doesn't need either sensor.... so this works fine for the 2009+
