Detailed Description
The K&N KN-198 oil filter is engineered for powersports engines that require consistent oil delivery and filtration under demanding operating conditions. Its synthetic-blend media is designed to work with common oil types, while the spin-on format and welded hex nut simplify routine service.

What It Helps Address
- Restricted oil flow caused by a clogged or inefficient filter
- Engine contamination from wear particles and debris
- Hard-to-remove filters during routine oil service
- Oil drain-back after shutdown that can delay lubrication on restart
- Pressure fluctuations during demanding engine operation
Installation Notes and Tips
Verify thread size, gasket sealing surface, and filter clearance before installation. Apply clean engine oil to the gasket before tightening, and follow the vehicle manufacturer’s service procedure for torque and oil change intervals. For fitment-based searches, use the KN-198 part number and confirm the M20 x 1.5 thread specification against your service manual.
