Just received this from K&N about their oil filters. Can this be true, that a filter can flow this much and still have a 90% efficiency rating at 10 microns?
Our oil filters would be considered high flow and high capacity. They flow 12 - 16 GPM depending on size and trap / hold 90% more debris than standard filters. This translates into a life of 6,000 miles. (We do recommend you follow your manufacturers oil change intervals). They have a 550 PSI burst strength which is more than double that of standard filters. This makes them suitable for all racing applications. They filter down to 10 microns with a 90% efficiency rating (cumulative). No initial pass data is available but that is not a real world test either. Oil needs to flow without restriction or the purpose of the filter is mute. The inner filter media has metal end caps to ensure no debris can get back into the system. They have anti-drain back valves and pressure relief valves. On the end, there is a 1" nut for easy removal. This nut is drilled through to allow the use of a safety wire; great for off road racing.
