How many miles, on average, should I get from the Wix?

I switched to the Wix deep air filter on 10/12/2011. I now have over 34,000 miles on the air filter and the Filter Minder is not showing any signs of restriction. Before changing to the Wix Deep Filter, I was using the Amsoil EaA189 OE filter replacement. I was averaging about 22,000 miles on the Amsoil EaA189 before it showed restriction per Filter Minder.

According to Amsoil, their OE replacement starved the engine of air, hence why they discontinued it. They now recommend the WIX. You can see the difference between the discontinued Amsoil vs the WIX.

Ever since the filter was installed, and according to my UOA report, the silicon number keeps getting lower. It sounds like some of you would recommend changing the filter regardless of what the Filter Minder is indicating? STONR, you have 42K on your Wix filter. I've got 34K on mine. My truck is pretty similar to yours in that I drive on the highway 99% of the time. I suppose the filters are cheap, so why am I debating this. :spank:

Thanks for the specs. Which filter are those specs for? Or is the Wix/Napa/Mopar the same filter?
