I read a test years ago by a heavy equipment mining company. they monitored everything down to oil analysis and precisely the amount of operational time each engine had when it had to be overhauled. Large Diesel engines. Turns out the aftermarket oiled air filters were killing engines at something like twice the rate of factory filters (won't mention brand). When you spend 50+k on a rebuild having your engines die in half the hours is a huge unnecessary expense.
I have never used personally or advocated the use of anything but OEM or equivalent filters since reading of that test. My Insight had one when I got it and the 02 sensor died at 36k miles. I would be willing to bet the over oiled filter was the cause of the bad 02 sensor.
