Utilizing the filter original designed for HKS Oil Filter and increasing its filter surface area by 15%, compared with a conventional product, greatly improved particle collection performance.

HKS Oil Filter's minimum particle size is 20 Micron compared with 25 Micron of JIS standard which corresponds to the filtration performance requirement of most engines. It is recommended to replace a filter every 10,000 km or 6 months under the normal driving environment. For sports and/or race use, it is recommend to replace a filterevery 3,000 km - 5,000km.



Compatibility: Please confirm that the filter unit size of 68xH65 / 74-H85 / 65-H50 and screw size. Installation to a vehicle which does not meet the conditions may result in engine damage due to leakage of oil.



Diameter of Oil Filter Screw: Make sure to select a proper oil filter screw size. Since both screw sizes are very close, M20 filter fits on UNF center bolt. If improper screw size is selected, it may cause the leakage of oil.



What is UNF screw?

It is a triangular thread form by inch in the ISO standard. The thread angle is 60 degrees. It is classified by the suffix "UN". The type of screw is described by a pitch as "Coarse" (UNC), "Fine" (UNF), "Extra fine" (UNEF). There is also one for aerospace equipment (UNJ). In Japan, use of this screw type is limited only for aircraft and automobiles, but it is widely used in the United States. JIS employs only coarse (UNC) and fine(UNF) pitches. This screw was initially designed for the military needs by the United States, the UK, and Canada.
