K&N Motorcycle Oil Filter KN-204C — Synthetic Media, Wrench-Off Nut for Faster Changes

The K&N KN-204C is a heavy-duty motorcycle oil filter built with synthetic media and an integrated wrench-off nut for faster, long-lasting engine protection.

The KN-204C is designed for powersports applications where sustained oil flow and reliable contamination control matter. Constructed with premium synthetic filter media, robust housing, and a part-specific bypass valve, this unit balances filtration efficiency with the oil flow rates modern motorcycles require. Riders using synthetic, conventional, or blended oils will appreciate the service interval potential and the convenience of the welded nut for quick changes on the road or in the garage.

How does this filter protect modern motorcycle engines?

The KN-204C captures particles while allowing steady oil circulation so bearings, cams, and gears stay lubricated under varied riding conditions. Its synthetic media provides high contaminant-holding capacity, and the reinforced construction resists collapse under pressure.

• Premium synthetic media for higher dirt-trapping capacity
• Uniform pleats maintain flow without excessive restriction
• Engineered bypass/relief valve prevents oil starvation at high viscosity or low temperatures
• Durable canister resists burst and deformation

What makes oil changes faster and easier with the KN-204C?

This filter includes an integrated welded nut on the end cap so you can use a standard socket or wrench to remove the unit—no strap wrenches needed. That mechanical advantage speeds roadside or shop service and gives a more secure grip when the filter is tight.

• Welded wrench-off nut accepts common sockets
• Textured end-cap for hand-starting installations
• Service-friendly thread and sealing surface for reliable reinstallation

How long will the KN-204C last and which oils can I use?

The filter is engineered to provide extended durability and compatibility with a wide range of oils. When paired with proper maintenance and suitable lubricants, it supports long service intervals by retaining contaminants and preserving oil flow.

• Recommended for use with synthetic, conventional, and blended oils
• Designed and tested for long-life operation under powersports conditions
• Laboratory-validated capacity and burst-strength performance

Which motorcycles are compatible with this part?

The KN-204C fits many modern and classic motorcycles and scooters across Honda, Triumph, Yamaha, and other marques—covering sportbikes, adventure models, cruisers, and maxi-scooters. Always verify fitment by year, model, and engine to ensure proper fit.
