I have been noticing I have been getting worsening mpg on every fill up. Hand calculating of course. So I decided to take a look at air filter. Filter was extremely dirty so I ordered a new one and replaced it. Went is Mann OEM filter. I also had some debris on the filter leading to MAF, I cleaned that out. Then took her for a drive and noticed a difference, seems like the motor can breath now. My question is I am thinking of replacing the MAF sensor, should I buy the OEM sensor or try the Bosch for $13 cheaper? I feel inclined to spend extra for OEM since Audi is a sensitive car.
