There is not any engine damage if the MAF was loose or wet. Not from that anyway. And I dont think the hydro shield would prevent what you had either. It did not suck up through the filter and get the MAF wet.

 

Anyone know how the sensors may have low input? If the water did not suck up through the filter I check and everything is secure?
