The AEM Induction 28-20385 is a panel-style drop-in filter for the factory airbox, built on AEM's Dryflow platform. It is an AEM Dryflow panel air filter made of non-woven synthetic material. The manufacturer's listing names Ford F-150, F-250 and F-350 trucks for 08-10 and Expedition for 07-10. Owners searching for a 2008-2010 F-150 5.4L V8 intake filter or a no-oil panel filter for a 2007-2010 Expedition should check the exact year and engine before ordering, because fitment ranges vary between sources.
The main reason to pick this filter over a stock paper element is reusability. The manufacturer says the filter is engineered to boost horsepower and sharpen throttle response. It is washable and reusable, so it can be cleaned instead of replaced. The manufacturer also says it holds up in harsh, dusty conditions. The limited lifetime warranty does not void the vehicle's warranty, which matters for buyers who want an upgrade without giving up coverage.
No. The manufacturer designs Dryflow filters to run without oil, so you clean the filter with AEM's Dryflow cleaner rather than re-oiling it.
The manufacturer's cleaning procedure applies whenever servicing is due and does not set a fixed mileage. Owners on user forums report cleaning about every 3,000 to 5,000 miles when driving in dusty or off-road conditions.
According to the manufacturer, the filter will not void the vehicle's warranty.
This is a beginner-friendly swap. The manufacturer rates the DIY level as easy, lists a screwdriver as the only tool needed, and estimates about 20 minutes for the job. To service the filter later, the manufacturer's procedure is to tap off loose debris, spray the Dryflow cleaner on both sides with most of it on the dirty side, let it soak for about 10 minutes, and rinse from the clean side outward. Let it dry naturally, or use compressed air carefully to speed drying, then reinstall once the filter is dry or only slightly damp. Confirm your year and engine against the manufacturer before ordering, since fitment details vary by source.
