In their July 2013 issue, Aviation Consumer published their choices for best products of the year. Among those products honored, Tempest was selected as the best oil filter. Aviation Consumer chose Tempest for its unique by-pass valve design, filtering ring magnet and "best of all - its lower price."
A few months back Aviation Consumer published a video demonstrating their comparison of Tempest oil filters to the competition. If you missed the video or would like another opportunity to watch it, please click here.
