Does anyone know what tool is required to replace the MAF sensor?

 

Ideally it is one of those Tamper Proof Star bits as I recall. But I used a screwdriver that was the correct width to fit, I think bluecoupe told me Beaner had found this idea.
Now I have the bits but not when I needed one.

 

Thank you !!

 

If I remember correctly, it is a 5 point torx. James
