Hi guys,
couple of questions... I'm looking to install a BMC CDA air intake.
The model that i'm looking at says it's specifically for cars that have a MAF part number of PBT-GF30. I checked mine and it says PBT-GF on the top, but nothing else?? Does anyone know if there were multiple versions?

Also, given that I plan on removing the factory airbox, I notice it has a sensor of some description on the side. What's this for? Does it need to be retained?

Cheers guys!!
