986 / 996 / 987 / 997 LN Engineering Spin-On Oil Filter Adapter 1997-08

106-01 Filter adapter, allowing for use of a conventional spin-on oil filter, rather than requiring the use of expensive and inferior replacement cartridge-style filters. The LN Engineering Spin-On Oil filter adapter also helps improve the longevity of your engine by providing full flow filtration, which means 100% of the oil gets filtered without having oil bypass the filter (as the factory filter housing allows for). Our design eliminates the factory bypass for the filter (engine still has a pressure relief in the oil pump to prevent over pressurization).
