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.

I've got 42k mi on mine. I can suck the filter minder down about 40% on WOT, but could get it to register about 20% if not more when it was a brand new filter.

My truck pretty much sticks to the road and doesn't see much dirt.

I would not use anything but the Napa Gold/Wix 49946 filter in the stock airbox. Hastings also sells an equivalent part# AF1492.

I replace mine minimum of once a year whether it needs it or not.

And I'd never put too much faith in those filter minders for telling you when to change your filter. I've had some pretty bad filters come out of trucks and equipment that were packed full of sand (including one that smoked a turbo it was so plugged up) and the filter minder gave no indication the filters were bad. Don't think I've ever personally seen on work properly.

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?
