This is modelled this to fit to the original mass airflow sensor with the original screws too. 

I needed to put an heatsink to the  Ignition amp so it stays cool.
Printed with PETG. 0.28mm “superdraft”. 100% infill. 
 

It might work with no problems or it might set your car on fire, so ymmv.  
This is my first 3d model i've made, so it might not be the best one around.
