Why choose a K&N motorbike oil filter?

A quality choice over standard filters

Unlike original filters or generic models, K&N motorbike oil filters are designed for the most demanding conditions: sports driving, track use or long journeys. Their ability to retain particles and their resistance to pressure guarantee extended engine life. The welded hexagonal nut is an added bonus: no need for a special filter remover!

Recommendations for use

For optimum efficiency, we recommend replacing your K&N oil filter at every oil change, i.e. every 6,000 to 10,000 km depending on use. Combine it with a quality motorbike engine oil to maximise the lubrication and protection of your engine. See our complete selection in the motorbike engine oils category.
