Review: Easy to clean. - Strong airflow. Exact replacement for original filter. Amazingly easy to clean. No variance in the functionality between the original and replacement.
Review: Great cone- shaped oil bath filter - This filter fits as a replacement for my factory installed oil bath filter in my 2009 Toyota FJ. It inserts into a plastic box near the power steering fluid jar in the engine bay. My original filter made it through about 280k miles but the rubber ends were deteriorating. Toyota does not carry a replacement, will only sell you a complete system. *Note: the fit is just a tiny bit snug, but worked. Measure your existing filter and compare, I dont know if differing systems were installed.
