AFE seems to be by far the best filter in the test, given that it had the 3rd lowest DP at 350SCFM and also passed the third lowest amount of dirt. Granted its resistance increased exponentially with dust loading, but that just means you change it frequently. The “No Brand” could be argued to be better as it has a slightly lower DP but it also passes slightly more dirt. Although it also had a much slower climb in restriction relative to how much dust loaded onto it. :shrug: Either/or. :gotme: Although I really don’t like that they stopped the test at +10 inches of water for each individual filter. Should have stopped them all at a single DP. ---

:lol: This is making me wonder if the filter in my wife’s protege has ever been changed. No seriously, I just waxed it for the first time in its life this weekend. Fill the gas right before you run out, change the oil somewhat near when you can remember when it was only a few hundred miles overdue, repeat. That’s been that poor car’s life. :ohnoes: I think I’ll pick one up on my way home from work. ---

I changed the oil and looked things over this past weekend. Oil pan is rotting (it is a Ford afterall) but I’ll wait and change that in the spring when I change the oil again. Coolant looked good, wires looked good, belts looked good. Just forgot the air filter. One of the brakes is dragging, but I’m sure they will all be dragging by spring. Her car has only passed inspection once without needing new brakes. Probably a result of her never washing it. (Seriously, maybe twice in 4 years.) Now that we’re married I’ll take ownership of maintaining it. Gonna replace the oil pan in the spring and get 4 new caliper carriers and 4 new calipers if necessary. Then start washing the damn thing once in a while so stuff stops seizing/rotting. :hang: As it should be. :shrug: It’s her job to sit there and look pretty and my job to take care of the cars. Now if I could just get her to bake me a pie… ---

The AEM dryflows are a paper cone instead of wire mesh and oil… supposedly they flow just as well but filter 99.53% and as small as 1micron… [http://www.aempower.com/filtration.aspx](http://www.aempower.com/filtration.aspx) i’d like to see some independent tests as well though [Next page](https://forums.speedlife.net/t/interesting-read-on-air-filters-k-n-takes-a-beating/38986.md?page=2)
