Ken Jones started designing the oil pump filter adapter in 1989 as a CNC Operator, Fabricator and Mad Hatter. For 10 years he worked on a few prototypes until finally coming up with the final design. He machined (CNC) the adapter in 1996 and installed the adapter on his custom 1978 Shovelhead. Ken developed this product to make oil changes easier and to prevent foreign particles from entering the engine, improving longevity of the motor. The adapter also has an added benefit of routing oil through the filter back into the motor. This eliminates the remote oil filter, oil lines and bracket. The filter simply spins right onto the pump.
