Mass Air Flow Sensors Reviews

The ease of removing my old air sensor and installing my new mass flow air sensor was very easy, no problem with any of the steps. The results have been seen more in the city and same result on the high way. I am still seeing an average of 30-31 mpg on the highway but an increase in the city from 24 to about 26. I only been able to run two tanks of gas so we will have to see if something else in MPG changes. I have seen a slight increase in horse power from the stop position and an increase in rate of excelleration on the high way. I step on the peddle and before i know it im doing 100MPH!! I'm not sure if it was worth $300 dollars but it will eventually pay itself off, so what can i loose.
