You can use the Mobil 1 M1-209 filter on the Toyota Camry / Corolla engines, both 4- and 6-cylinder. Using this size filter increases the volume of oil in the sump by 0.27 quart (8.64 oz) over the M1-103 (or other manufacturer's equivalent - Purolator PureOne 14476), and increases your filter surface area significantly (almost double, although I am not exactly sure of the sq. in. difference). The O.D. of the filter gasket is a bit larger than the M1-103 (Purolator PureOne 14476 / 14477), but still fits on the mating surface well enough to prevent leaks. I am not making this statement based on anything I have been told, but instead on what I am actually using an oversized filter (same size as M1-209) right now on my 2006 Toyota Corolla (1zzfe) and my girlfriend's Camry (5sfe), and have been doing for a while.
However, I would have to agree with Pablo that I prefer AMSOIL filters for my car (Corolla EaO34, which is same size as M1-209).
