The AEM Induction 28-20387 DryFlow is a red, panel-style replacement for the factory engine air filter on Toyota Tundra, Sequoia, and Land Cruiser applications. The manufacturer builds it on its oil-free, non-woven synthetic DryFlow media, which it describes as washable and reusable for the life of the vehicle. It is made in the USA and carries a limited lifetime warranty, and the manufacturer states that installing it will not void the vehicle warranty.
The reason to pay more than a basic paper element is durability and reuse. The manufacturer says the filter captures up to 99% of harmful contaminants and performs in dusty conditions, and it claims the design increases horsepower and throttle response. Owners on user forums report no rise in silicon readings during used oil analysis after running DryFlow media, and a few mention a tangible throttle feel, though gains vary by vehicle. Because it needs no oil, you avoid the oil-coating step of cotton gauze filters. Fitment deserves a careful check. The manufacturer's listing names 2007-2010 Tundra, Sequoia, and Land Cruiser, but other fitment tables show wider year ranges, so confirm your exact year, trim, and engine before ordering. Installation is a drop-in job that owners describe as snug, and the manufacturer lists about 20 minutes with a screwdriver.
No. The manufacturer states the DryFlow media does not require filter oil, so there is no oiling step after cleaning.
Yes. The manufacturer describes the filter as cleanable and reusable, and owners on user forums say they wash it with AEM's cleaning solution and reinstall it rather than replacing it each service.
The manufacturer states that installing this filter will not void the vehicle warranty.
This is a drop-in panel filter that replaces the factory element inside the stock air box, so no cutting or modification is involved. The manufacturer lists a 20-minute install that requires only a screwdriver for the air box cover. Before you start, read the manufacturer's installation instruction sheet, and check that the filter sits flat and fully seated in the box so the airbox clamps close without pinching the media. Owners on user forums describe the fit as snug, so take care when reseating the filter to avoid tearing the edge seal.
