S&S Cycle 31-4103A High-Performance Black Oil Filter for Harley-Davidson

The S&S Cycle 31-4103A is a high-performance oil filter engineered to provide superior engine protection for Harley-Davidson Twin Cam and Milwaukee-Eight engines. Designed to maximize engine life by maintaining clean oil between service intervals, this black oil filter offers advanced filtration technology that outperforms stock filters.

Key Features:

• 10-micron filter media traps smaller particles than stock filters while maintaining low restriction to oil flow
• Direct bypass valve design routes bypass oil directly to the filter exit, preventing contaminated oil from passing over dirty filter media
• Sturdy steel canister construction houses premium filtering media and internal components
• Smaller diameter than stock filters for easier installation and removal
• Black finish for a custom, low-profile appearance

Regular oil filtration is your first line of defense against friction wear particles and combustion byproducts that accumulate between oil changes. The S&S Cycle oil filter captures contaminants more effectively than standard filters, ensuring your engine oil stays cleaner longer. Compatible with 1999-2018 Harley-Davidson Twin Cam 88/96/103 models and 2017-up Milwaukee-Eight engines, as well as all S&S X-Wedge engines.
