CSF 14-18 Subaru Forester High-Performance All-Aluminum RadiatorThe 2 Row 42mm aluminum core not only increases the fluid capacity of the radiator, but also improves the cores ability to dissipate heat. CSF's Exclusive B Tube Technology increases the heat transfer by approximately 15% over regular oval welded tubes. In addition, the super efficient multi louvered fins maximize airflow through the core for the best possible performance. Efficiency is key in off roading as speeds tend to be lower overall so you end

Just installed in a 2006 4Runner. Can’t speak to exact filter partials or longevity, but what I can’t say is that it fits very well and looks to be made very well. It actually fits better than the Bosh filters I normally use. Has a nice foam seal around all 4 edges and fits in the tray perfectly. Seem to be a nice option. So if you have a 03-09 4Runner it’s going to work well. Here’s some pictures of this filter (the blue one) next to a Bosh filter I removed. Also a picture with it in the factory tray.
