Make sure you have tamper proof torx sockets if you are just replacing the insert like Bosch provides for about $ 77.00.

You can use needle nose pliers to grip the torx screws form the outside and muscle them out.

The Bosch inserts provide you with new phillips screws to back in with.

Also make sure you replace the engine air filter and take the air box out and clean all the debris out.

You can replace the mass airflow sensors all day long, but if your engine air filter is is bad shape, it can trash your new air mass sensor within days.

Been there done that, always replace the engine air filter too, always, did I say always?

Clean the dust and debris out of the airbox, and make sure you don't get any dirt down the inlet tube in the process.
I cover the tube opening with a lint free towel while exposing it during repairs.
