The Spin On filter adaptor omits the factory bypass that diverts bypass oil around the filter at start up and at times of higher than normal oil pressure. During these periods the factory filter does not filter 100% of the oil. Tis is also even more true if the factory bypass spring has lost tension due to high oil temps or time in service.

The factory filter does not filter 100% of the engines oil at all times, so any debris that is suspended in the oil will take out more components. This is especially true if you are injecting debris filled oil into the IMSB.
