K&N Motorcycle Oil Filter KN-198 — High-Flow Synthetic Media with Wrench-Off Nut

The K&N KN-198 motorcycle oil filter is a heavy-duty, high-flow replacement filter engineered with premium synthetic media and an integrated wrench-off nut for faster, cleaner oil changes.

Designed for powersports and select Polaris and Indian models, this K&N Performance Oil Filter pairs robust construction with high-efficiency filtration to help protect engines while maintaining strong oil flow. Built to withstand the demands of recreational and utility riding, the KN-198 uses uniform pleat synthetic media and a model-specific bypass/pressure relief valve to balance filtration efficiency and reliable oil delivery. Its welded wrench-off nut simplifies removal so routine service takes less time and creates less mess.

How does the KN-198 improve engine protection during extended rides?

The KN-198 uses premium synthetic, high-efficiency filter media with consistent pleat spacing to capture contaminants without overly restricting oil flow. That combination helps preserve engine components over long intervals while supporting sustained performance under load.

• Premium synthetic media traps fine particles while maintaining flow
• Uniform pleats increase contaminant-holding capacity
• Tested for burst strength and capacity in lab conditions
• Compatible with synthetic, conventional, and blended oils

What makes oil changes quicker and cleaner with this filter?

The KN-198 includes an integrated, welded wrench-off nut so you can use a standard socket for removal—no separate cap tools required. That feature reduces the time spent wrestling with stuck filters and minimizes contact with dirty oil during service.

• Welded nut accepts common sockets for fast removal
• Sturdy shell and seam design resist deformation during installation
• Designed for easy hand-tightening to factory specification
• Reduces spill risk and speeds routine maintenance

Is the KN-198 compatible with my vehicle and oil type?

The KN-198 is an application-specific, direct replacement for many Polaris Ranger, General, RZR and Indian FTR models from recent years; check fitment for your exact year and trim. It is engineered to work with premium synthetic oils as well as conventional and blended formulations.

• Direct factory replacement where listed for ease of fit
• Optimized bypass valve for high-end synthetic oils
• Wide compatibility across Polaris and Indian model ranges
• Refer to vehicle fitment list before purchase

How durable and reliable is this filter under heavy use?

K&N builds the KN-198 with heavy-duty construction and subjects it to laboratory testing for burst strength and capacity to ensure it holds up under demanding conditions. The robust shell and media resist collapse and maintain performance across extended intervals.

• Heavy-duty canister construction for structural integrity
• Lab-tested for capacity and burst strength
• Performance-engineered bypass/pressure relief valve specific to part number
• Rated for up to 20,000 miles under recommended conditions

Who is this filter for? The K&N KN-198 is aimed at riders and owners of compatible Polaris and Indian powersports vehicles who want a high-capacity, durable oil filter that simplifies maintenance and supports longer service intervals. It suits weekend trail riders, utility vehicle owners, and enthusiasts who prefer premium synthetic oils and want a direct-fit replacement that combines strong filtration with fast, clean serviceability.
