Technical Details and Features

The K&N KN-198 oil filter features high flow premium media that efficiently traps contaminants while allowing optimal oil flow. The anti drain back valve prevents oil from draining out of the filter when the engine is off, reducing wear during startup. The built-in bypass valve and PSI relief valve ensure continuous oil circulation even if the filter becomes clogged or oil viscosity changes due to temperature. The nitrile rubber gasket provides a reliable seal to prevent leaks, and the spin-on design with a 17 mm removal nut simplifies installation and removal. With a height of 3.797 inches and an outside diameter of 2.563 inches, this filter fits specific engine applications requiring M20 x 1.5 threading.

Compatible Vehicles and Applications

The K&N KN-198 oil filter is compatible with various makes and models that specify an M20 x 1.5 thread size and require a spin-on oil filter with these dimensions. It is commonly used in certain European and Asian vehicles, including select BMW, Volkswagen, and Audi models. Always verify fitment with your vehicle’s specifications before purchase.

• Prevents engine wear caused by contaminants in the oil

• Maintains consistent oil pressure under high load or temperature
• Helps avoid engine damage from clogged or restricted filters

Installation Notes and Tips

When installing the K&N KN-198 oil filter, ensure the engine is cool and the old filter is fully drained before removal. Use the 17 mm removal nut to loosen or tighten the filter without damaging the housing. Apply a thin layer of clean engine oil to the nitrile rubber gasket before installation to ensure a proper seal. Tighten the filter according to manufacturer torque specifications to avoid leaks or damage.
