K&N Motorcycle Oil Filter KN-199 with Welded 17mm Nut — High-Flow, Heavy-Duty Protection

The K&N KN-199 motorcycle oil filter is a heavy-duty, high-flow replacement designed to protect powersports engines up to 20,000 miles while making oil changes faster with an integrated welded nut.

Built for riders who demand durable filtration and easy serviceability, this K&N Performance Oil Filter uses premium synthetic media and reinforced construction to withstand racing, off-road use, and long touring intervals. It balances high oil flow with efficient particle capture, and the welded 17mm nut speeds removal in cramped engine bays. The filter is compatible with synthetic, conventional, and blended oils and is engineered with a part-specific bypass/pressure relief valve for consistent operation under varying conditions.

How does the KN-199 improve engine protection?

The KN-199 combines uniform pleated synthetic filter media and a robust canister to trap contaminants while maintaining steady oil flow. Its construction is aimed at minimizing bypass risk and preserving oil circulation so moving parts stay lubricated under load.

• Premium synthetic media with consistent pleat spacing for efficient debris capture
• Part-specific bypass valve to prevent starvation during heavy flow or cold starts
• Heavy-duty metal canister and reinforced baseplate resist deformation

Will this filter survive off-road and high-stress riding?

Yes. The KN-199 is engineered for extreme conditions with a leakproof double-rolled seal and high-burst-strength components that hold up to vibration, mud, and high RPMs. Its durable shell and internal design reduce the chance of failure in harsh environments.

• Leakproof double-rolled seal prevents seepage in rough terrain
• High-burst-strength materials and reinforced baseplate for durability
• Construction rated for aggressive riding and motorsport demands

How does the welded nut make maintenance easier?

The KN-199 includes an integrated 17mm welded nut on applicable models so you can use a socket or wrench to remove the filter quickly, even where access is limited. This reduces the need for special tools and speeds service intervals on the trail or in the garage.

• Integrated 17mm welded nut for fast, tool-friendly removal
• Ideal for tight engine compartments where strap wrenches are hard to use
• Saves time during routine oil changes and track-day maintenance

Which vehicles is the KN-199 compatible with?

The KN-199 fits a wide range of powersports and motorcycle models from brands like Polaris, Arctic Cat, and Indian across model years listed by manufacturers. Always confirm fitment with your vehicle’s parts guide before purchase to ensure proper compatibility.

• Fits multiple Polaris RZR, Turbo, Scrambler and Sportsman models (2014–2024 ranges)
• Compatible with Arctic Cat Wildcat XX series and select 2018–2024 models

Who is this for? The K&N KN-199 is aimed at riders and mechanics who want a reliable, long-lasting oil filter that handles high-performance and off-road demands while simplifying routine maintenance. It suits owners of compatible Polaris, Arctic Cat, and Indian machines who use synthetic or conventional oils and need a rugged filter designed for extended service intervals and easy removal.

Features include long-life protection up to 20,000 miles, high-efficiency synthetic media for outstanding filtration and flow, heavy-duty canister construction, a welded removal nut for convenience, and a design tuned for high-end synthetic oil performance.

Before installing, verify vehicle fitment and follow oil change intervals recommended by your engine manufacturer.
