The aFe MagnumFLOW OER P5R (part 30-10162) is a drop-in replacement panel filter built on aFe's Pro 5R media. Its Pro 5R filter media features five layers of progressive oiled cotton gauze, and with up to a 17% increase in flow over stock, the manufacturer claims a measurable airflow gain over the factory paper element. The frame is polyurethane, which makes it extremely durable and simple to install. Because the filter is washable and reusable, a buyer can clean and re-oil it instead of replacing paper every service interval, which offsets the higher upfront price. Search terms this part targets include 2009-2012 F-150 4.6L 5.4L 6.2L oiled cotton air filter, reusable drop-in intake filter, and Pro 5R restore kit.
Per the product name, this filter is sized for the 2009-2012 Ford F-150 V8 engines (4.6L, 5.4L, and 6.2L). The manufacturer's own product listing shows a broader F-150 V6/V8 application, so confirm the fit against your VIN before ordering. The filter is designed to sit in the factory airbox housing, and the deep, open pleats allow for increased surface area, flow, and dust holding capacity. Installation is a straightforward swap with basic hand tools, and cleaning is simplest with aFe's Pro 5R restore kit, which includes filter oil and cleaner.

This is a beginner-level job. Owners on user forums describe the airbox procedure as needing only a Phillips screwdriver and no special tools. Disconnect the mass airflow sensor connector first, then loosen the intake clamp and remove the airbox cover. Handle the MAF sensor carefully, since it can stay attached to the housing lid. Lift out the old element, then check the orientation of the new filter against the old one before seating it. Make sure the bump seal sits flush all the way around, then reattach the cover and clamp. Confirm the airbox is fully sealed before starting the engine.
