Originally developed for demanding race applications, K&N Performance Gold? Oil Filter is rapidly becoming a favourite among customers for its durability and easy removal. Each oil filter comes with a 17mm nut welded to the top of the canister so they can be easily removed with a spanner.
To satisfy the demands of Racers and Track Day users, our oil filter has many features over and above the requirements of most vehicles. We use thicker canister walls for extra strength and durability which reduces the risk of damage from loose rocks and debris. The drilled hole on the nut provides for safety wire attachment. K&N oil filters also use a resin impregnated cellulose filter media. This allows for higher flow rates while providing outstanding filtration.

K&N Performance Gold Oil Filters use a cellulose media bound by phenolic resin surrounding a metal inner core that provides structural strength to reduce the risk of filter collapse. The resin is the "glue" that holds the media fibres together and at the same time keeps "pores" open by keeping the fibres apart. The resin is cured to full strength during the element manufacturing process. Phenolic resin systems are an excellent choice for the high temperature demands of oil filters. The GTO/3000GT filter includes an anti-drainback valve, which prevents oil from draining back into the crankcase during engine shutdown. The anti-drainback valve is useful in situations where the filter is mounted horizontally which could allow backflow. K&N use rolled threads to help prevent stripping during installation or removal and an internally lubricated gasket provides a positive seal even after the filter has been removed and reinstalled.
