S&S CYCLE - 31-4103A - Oil Filter - Black
Whether restoring a machine to factory spec or building something better, the S&S CYCLE 31-4103A gives you an oil filter that meets the demands of serious street use. Sturdy steel canister houses the finest filtering media and internal components available. Canister is slightly smaller in diameter than stock filters to make them easier to remove and install, giving you a level of quality that holds up across the full service life of the component. Designed with a direct bypass valve that routes bypass oil directly to the filter exit, which minimizes the amount of contaminants carried to the engine in the unfiltered bypass oil. The nominal particle capture size is smaller than that of stock filters while the resistance to oil flow is nearly the same. Includes drain plug O-ring with filter. The 31-4103A is the kind of component that earns its place in any build or repair by doing exactly what it is supposed to, every time. Sold individually.
