Standard STP air filter out
Premium STP air filter in
Not entirely sure how many miles on the last filter - my guess is 35-40k. I just can't seem to recall if I changed it a few years ago or not. I have dusted it out, and cleaned the airbox, at least twice.
Probably over paid for it, but decided to get the premium STP air filter this time around. Not sure if it'll make much, if any difference. Compared it to Fram, and some other filters, and it seemed pretty well made. It is lightly oiled paper filter (not like K&N reusable oiled). Supposed to have greater air flow, with just as good or better filtering, due to the oil. Probably marketing, but we'll see.
This filter is rated at 12,000 miles (as are most replacement air filters). But owner's manual says 45,000 per change. I'm sure I'm good going over 12,000. But curious what y'all think about going to maybe 20,000 or more? Trust the filter or the car manual? Or some happy medium.
