Nobody is doubting the quality. Even the best quality built filter can be problematical if it does not meet the correct specs for a particular application.
The issue is that it may not have the correct anti-drainback or pressure bypass characteristics. Especially the anti-drainback valve behavior. For example, the FL1A filter appears to have between 3-4 times lower Bypass Valve Opening Pressure than correct spec. Mann W 940/4.
