A full throttle run to redline might have changed that.Filter minder was still in the green
Right size for a honker size engine in a honker size truck...That’s a honker sized filter!
It's just another air inlet. Of the 2 its the only one with a prefilter (the foam). Not sure the reasoning behind it because that will be hot engine air but I am sure Ford had a reason.In the last photo, the inlet seems to be at the bottom right of the airbox. What's with the other hole covered by foam?
Indeed I didMan you sure got your money's worth!
That sucks Do you work in dusty environments? All the super duty's I have owned have been reasonably good with the air filters. I have only had 3 if I remember right you manage a lot more.The ones in the 6.7L trucks at my work pull the restriction guage down by 10 k
I'll try and remember to quit just letting the truck sit and idle and actually use it. Sarcasm aside, this truck gets used constantly and often tows heavy so it gets plenty of throttle. I'm not easy on it, just shy of abuseA full throttle run to redline might have changed that.

I mean, they're your vehicles but meh. I also don't adhere to the manufacturers' OCI or maintenance reminders on things like mileage either though. There's a huge difference in "changing it too often" at like every 10-15k and thinking people are changing it too often and going 100k on it. In the Midwest, there's no way in heck we could go 100k on an air filter. Must be that clean air in TN.Why? My UOA's never showed excessive dirt and my filter minder never went into the red. Personally I think people change their filters to often

Looks more like a way to block that hole in the corner of the airbox. Maybe they don't want any engine bay air to come into the airbox - ??.It's just another air inlet.

That's true of most people who don't frequent dusty areas. In choosing their recommended filter replacement intervals, vehicle manufacturers have to assume near-worst-case conditions. Not the worst, but maybe 95th-percentile worst. Everybody else can safely go farther.Why? My UOA's never showed excessive dirt and my filter minder never went into the red.
