"Why did Jaycee discontinue the billet racing filter ? Is it because the mesh is almost impossible to get totally clean (as posted earlier) hence why the new speedflow has the throwaway element ?"
Jack was unable to source the original filters so we decided to start from scratch and build it exactly the way we wanted, one improvement was the ability to use a smaller micron, disposable element as well as the anti back flow valve and easy to access removeable cap.
Can you put the new disposable element that is is used in the latest speedflow filter in the older JayCee filter with the "cleanable" element? That would be nice because then those of us who have an older JayCee filter with the cleanable element wouldn't have to buy a whole new filter.
