The non-TDI oil filter, the B, has a spring tension of about 15-lbs for the bypass valve.
The TDI oil filter, the E, has a spring tension of about 35-lbs for the bypass filter.
This higher spring tension is only an issue if you use a high viscosity non-synthetic oil in winter, say a 15W-40 or a 20W-50. The bypass valve insures that there will be oil flow to the engine during cold starts.
The Baldwin B114 is a replacement for the E filter. It uses the 35-lb spring in the bypass valve. I use the B114 in my car.
