Most filters in the aftermarket not all, use oil. They are most likely talking about the wire of the Mass Air Flow sensor getting oil on it and not reading the air flow correctly, which helps computer to control air/fuel mix.
I have never had that problem but, if You had a problem You can use alcohol and a Q-tip and gently clean it off.
After cleaning the oil filters and reoiling You are supposed to squeeze all the oil out that can prevent this. If You do not squeeze excess out enough it will not take long for it to lose the excess and then clean the tiny wire.

I have been considering changing my air intake also but have become concerned in the past week with something I read (here I think) that Hummer had directed the dealers not to replace oil soaked something sensors that are getting wet from the oil needed on some of these elements. Which ones of the air intakes use oil as part of them?
