How does one know when it's time to change the air filter. Miles and age are not good reasons to simply throw away a good filter. It's all about how much dirt the filter has trapped due to the driving conditions. Do you drive in dusty places or urban near city's. As the filter medium collects more dirt it's actually better at trapping the dirt, yet needs to flow air unrestricted. The only way to check for a 'clogged' filter is to check for a pressure difference across the filter. Filter minder has made these for years, this one I bought used at an auto recycler (junkyard) only cost me $5.00. Gm and Ford has used these on late model trucks for years.
The install is simple. Locate a spot on the clean side of the filter. Drill a hole the size of the ID of rubber grommet, not sure of the size but it's near 7/16 so maybe have to use a file to enlarge. Before drilling check to make sure the hole is centered between the ribs inside the air box.
