I have a 1990 Volkswagen Jetta GL 4 Cylinders A 1.8L FI SOHC and I am trying to figure out what I am to do with the Mass Air Flow Sensor on my car and what application to use to add it to K&N Apollo RC-5052AR "CAI" setup. I am kinda stumped. If you could provide any information that would be greatly apreciated.
