Halloween comes early

I engaged my bookish 10-year-old son in helping me with this simple but important piece of regular maintenance, that no one should pay a dealer to perform. I mentioned how the manual stresses keeping things clean - placing towels over intake, being careful to avoid getting any byproducts of the filter change into the MAF etc. The Audi manual points out how dirt introduced via intake can lead to major problems.
Then I got the housing apart and saw the AF element in this car. Scary.
