Cause of MAF sensor failure
I was talking to my mechanic about why the mafs go out so often on the boxsters. He enlightened me the fact that the sensors can burn off just about anything except silicone. He said the silicon that is on the road surface or directly from your tires gets sucked in through the air intake and sticks to the metallic parts of the sensors. This is what causes them to go bad. He also pointed out that the stuff I was using to make my tires look wet has silicone in it. I have stopped putting the stuff on my car. I even used to shine up the vents on the air intake. So if you are going through maf sensors this may be the cause. Thought I'd put it out there.
