K&N premium oil filters were originally developed for demanding race applications and are fast becoming a favourite among consumers for their easy fit and removal and for their durability. Several of the product development technicians at K&N are sports class racers and insist on filters that correct the issues they have experienced over the years.
K&N powersports oil filters are TUV product endorsed and TUV factory production monitored. Our filters contain a modern synthetic filter media, designed for ultimate flow with less pressure drop, yet engineered for outstanding filtration. K&N powersports ‘spin-on’ oil filters feature a heavy-duty metal can. Most of these have a 17mm nut affixed onto the end that allows for easy installation and removal. The 17mm nut is crossed-drilled so racers can safety wire the filter to their bike.


  • Includes a new high-quality rubber anti drain back valve
  • An improved pressure relief valve
  • A strong inner core
  • "Spin-on" oil filters feature a heavy-duty metal can with a 17 mm cross drilled nut.
  • A heavy-duty base plate with an improved rolled seal
  • Traps 99% of harmful contaminants

SHIPPING IS FREE* for orders of £75 and over , regardless of the weight of your order.
We've tried to keep all other shipping costs as low as we can.

Carriage starts at just £0.95 (inc VAT) for small items, with our most common courier rate set at £4.99 for orders of 5kg (enough for 5 litres of oil).

  • *Free shipping is available for UK Royal Mail, UPS Access Point™ (click & collect) and standard UK courier services (not express / priority / islands).
  • Courier surcharges mean we are unable to offer free "to the door" courier shipping from us in Cornwall up to Highlands / Grampian in Scotland - and because we send a lot of liquids, not every courier option is available to us. UPS Access Point™ (click & collect) is available as a free shipping option across Scotland, Wales and England, wherever there is a UPS Access Point™ Location.
  • Carriage charges are based on weight - please see our table of carriage costs for full details (although adding an item to your cart and viewing the calculated carriage is often easier!).
  • Priority shipping is also available.
