Does anyone know of a longer oil filter that has the same thread and 2.8 in diameter ? I have always used the fram 9837 but it is very short, i would like a longer one both for more filter material and ease of access.
What is the purpose of the anti drain back feature when the filter is oriented upward and therefore gravity can't empty the filter case? Am I missing something?However, keep in mind the bypass and anti drainback valves. Both have to be present and the bypass at the same pressure. A silicone anti drainback is preferred over the rubber one, especially in cold temps.
