Oil Filter Cartridges

Oil filter cartridges – disposable filters for the oil flow

Oil filter cartridges differ first of all in the thread used to screw them on. A possible second criterion is the length of the cartridge. Not all Harley models offer unlimited installation space. Color, finish or brand are only important in third place. Perf-form filter cartridges have proven themselves for Harleys. The standard thread for Harley oil filter cartridges is 3/4”, with two exceptions: FL and FX 4-speed models from 1982 and Sportster 1980-1984 had M16 threads and the V-Rod model series had M22 threads.

Why use disposable filters?

Before the invention of the oil filter cartridge, washable filters were quite common. However, the filtering efficiency of washable filters always depends on the treatment, i.e. who washes the filter element how carefully with which cleaning agent. The disposable filter is not as environmentally friendly or sustainable, but the advantages lie in the handling and possible warranty claims. The filter manufacturer guarantees consistent quality and – now we are definitely causing a shit storm – the engine manufacturer can rely on it much more than on the individual mechanic. And changing a cartridge takes only a few minutes, even for DIY mechanics, and saves costs.
