Will a induction kit kill the MAF sensor

 

some say yes some say no. I personally run one. What I would suggest is that you stay away from the oiled type though as these can foul the maf which can damage them/cause incorrect readings etc.

 

Same here i have an Apexi ik and its fine but also its very well secured against vibration which can damage the maf.
From what i've read on here some imprezas models have weaker mafs which can be more easily damaged.

 

If you intend fitting an induction kit, ensure you purchase one with all the mountings required to stop any travel and vibration.

Or else get some nice shiny brackets made up
