I have a 1990 35th SC, and noticed while looking at the MAF sensor it is a different design than the 1991 MAF I had access to. The '91 sensor has a much larger internal diameter, but has a center post. The 90 sensor has no such post, but a smaller main opening and secondary opening for the heated wire, both covered with a wire screen. For the sake of experimentation, I have been running the car (1990) with the '91 MAF. I have felt no discernable difference in driveability. I assume the redesign was for the better, but did not know if there were any compatibility issues that might cause driveability or mileage problems over time that aren't initially noticed. I did a search, and came up short. Any reason why I should not leave the newer style MAF on my '90?
Thanks
