Mas Air Flow Sensor
Can anyone tell me what size mas air flow sensor I have the #'s on it are XF2F-12B579AA & 9D09-1 & 7024631 & > PBT-CF30<. Also would It be a waste of money to go with a bigger one with just a K&N complete intake system. And what would be the biggest size I could go to?

If you have the K&N FIPK, I would go with a Granatelli 70mm Mass Air. Anything bigger than that, and you would have to start thinking about changing injectors to match. It will help, I don't know how much on the 4.0 though. I have a 5.0, and am running a K&N FIPK, an 80mm mass air, 24lb injectors, a Superchips, custom exhaust w/ Motorsport headers, an AIRAID throttle body spacer, and a couple of other things also done also. I had to send my chip back to them to have it recalibrated when I changed injectors and went to the 80mm from a 70mm. Might want to check with them on it...
Oh yeah - I think your stock size is either 55mm or 60mm. Not sure...
Good Luck and let us know what you do!!!
