Another vote for the end-cap type. Different filters that fit the 4Runner may require different size end-caps. On my son's Hyundai, the NAPA, Purolator and factory filter all take different sizes.
My approach for all my cars: Go to my friendly NAPA guy and get a Gold series filter for the new car. NAPA filters are made by Wix and are generally considered pretty good. Take filter out of box and ask the guy to find an metal end-cap wrench that fits. If that wrench won't remove the factory filter, bash an old screwdriver through it to get it off if it won't come off by hand. Then install new NAPA filter. (Of course, by now I have a half-dozen of these end-caps, so usually I have the right size.)
