K&N's high-performance oil filter has gained tremendous trust as a high-flow air filter. Excellent filtration performance and increased oil flow rate reduce pressure loss through the filter and improve engine performance. [Filtration Effect] By using cellulose material impregnated with resin, the filtration performance is 10 to 20 microns, and even ultra-fine metal powder can be removed. Like air filters, the accordion structure increases the area in which the oil that passes through comes into contact with the filter, improving the filtration effect. [17mm top nut (*cartridge type only)] The assembly replacement type has a 17mm nut on the top and can be easily removed. This makes maintenance and replacement extremely easy and quick. It also has a service hole for a wire lock, so you can use it with confidence even under harsh conditions such as racing. [Anti-back function] Equipped with an anti-back valve that prevents oil backflow when the engine is stopped.
