I have a Gen 2 which uses the same basic engine. I use the 4cyl Camry size filter, which is about 1/2-3/4 in longer, otherwise identical. Mobil uses the 103 for both applications, the shorter one. The 209 is too big, I see no reason to out think the factory to that extent. Toyota would tell you to use their larger filters if they were needed. I use the 209 on my Chrysler vehicle, it's much fatter. No way I would chuck that on my little 1.5 l engine, there is no reason for it. I ordered two Microgreen 101 filters which are the longer version. These should filter better than an M1 filter, according to their hype, but cost more, $15 each total. The main reason I went for the longer version as it puts the filter out a little more for easier reach.
