I found these high quality Japan made filters. Now if shipping was not so much I would give these a try.

Oil Filters
An engine running on dirty oil won't last. Keep it clean with JS ASAKASHI Oil Filters. It helps to capture harmful contaminants that can harm your engine before they can affect the performance, and life span of your engine. Oil Filter should not just filter engine oil but should do it with high level of efficiency without blocking oil flow and should preserve its quality for sufficient period of time. Efficiency very much depends on the quality and size of filtration media.
Using Plate spring and M-pleating of pleating media gives extended filtration area for compact size filters required by new vehicle manufacturers.
Parts of JS ASAKASHI Spin-on Oil Filter
Heavy-duty Case of drawn steel provides longer life and improved durability.
Anti-Drain back Valve - keeps oil in filter to prevent engine from destructive “dry starts”. It stays flexible in extreme temperatures.
Mounting Plate made of heavy gage steel prevents deflection (movement) at the gasket sealing surface and provides strong threaded attachment to the engine.
Inner Element made by "M"- type pleated, prescription-blended filter media provides more than adequate filter efficiency. The element has a controlled porosity blended media to assure complete filtration of the oil.
Plate Spring is used instead of commonly used coiled spring. That allows increasing size of the element within same size of the filer canister.
O-Ring Gasket exterior seal in between the filter and the engine body. Usage of height quality rubber ensures leakage free environment even in extreme temperatures.
By-pass Valve is a spring loaded valve assembly calibrated to certain pressure to prevent engine from becoming dry in case of high contamination of media or extremely low temperatures.
