So I sprung fo a nice filter minder at a really good price. I got the remote one for the Dodge 440. Well it arrived today. As I understand this this device it is supposed to detect and record the results of unwanted vacuum in the down stream side of my air filter. High or too much vac indicates that the filter is getting restrictive and shold be changed. N more changes ecause the calander or milews driven dictate. Now I change because it is needed and maybe that is early or late bt my mpg over the long haul should go up. Great theory, Huh?
SO WHY DOES MY FILTER MINDER MEASURE P R E S S U R E ? Help,please.
John without a clue. I can pry off the "exhaust port cover" and make it measure vac but I'm not sure...
