Why is the current version of the filter different from the previous one? The current version of the WL7422 filter does not have a bypass valve. The previous version of the WL7422 filter, due to the original filter manufacturer's patent, had a bypass valve built into the top bottom, which was connected to the valve in the engine casing, without affecting the function and filtration parameters. Why has the WL7422 filter design changed? The bypass valve has been removed as the original filter manufacturer's patent has expired and the original filter design solution can be used. Does the filter work properly? Both the previous and current versions of the WL7422 filter have the same functionality. The opening pressure of the valve integrated in the upper bottom of the filter was selected in such a way that it does not affect proper oil flow. The new version of the filter is already on sale, but there is still a version with a built-in valve in the upper bottom on the market.
