Can anyone PLEASE tell me the torx size for the Mass Air Flow sensor bolts on my R56 S. I just received my CAI and would like to install this weekend! Thanks and "KEEP MOTORING".

 

Just be smart and get the little screwdriver kit with a multitude of bit tips that is sold in any hardware store, including Home Depot For ~$10.----------- EDIT, To help you out futher the size that you require is T-30.

 

I think you might also need t-25 for the air box hold down bolt, #3 in this diagram:

Thanks!

 

the screws are not super tight....they are only screwed into plastic. You can use a flat-head screw driver to get them out with ease. If this were any other situation I would say "use the right tool for the right job" but....it is just plastic
