K&N oil filters due to their construction have gained recognition of the most demanding drivers and are one of the few used in competitive motor sport. These filters are distinguished by a filter layer which does not limit oil flow.

For screw-on filters, the benefits are:

  • Reinforced external wall construction reducing the risk of mechanical damage
  • Head for easy filter operation using standard spanners
  • The hole in the head allows the installation of the pin required in many motor sports disciplines

An additional advantage is the internal valve closing the flow after a pressure drop, which protects the engine against dry start.

K&N sports oil filters are an ideal solution for all car users who care about the efficiency and safety of their engine and are looking for the highest quality products.

The filter is dedicated to the following vehicles:

Great fit for a 2005 Honda Element
These fit my 2005 Honda Element perfectly. Solved a small leak issue. I’ve had these installed for about one season so far (winter into summer) and they are still holding up. The install is simple if you’re confident working on your power steering system. Overall happy. No complaints
