My first PurePower oil filter was on my 1995 H-D Wide Glide with 55,000+ miles, my second PP oil filter is still on my 2005 H-D Road King, which is going strong with 96,000+ miles, and my third PP oil filter is on my 2017 Road Glide with over 27,000 miles.
The first PP oil filter was removed from my Wide Glide after I wrecked it and sold to a friend who still has it on his H-D.
I do my own service and have never had a problem with the filters. Any time, while on my trips, I've had someone else do service I make sure they know about the filter ahead of time and to be careful of the O-rings.
Great products. Works just like advertised, no BS. I can't comment on service or guarantee BECAUSE I've never had a problem with any of the PP filters I had/have. They are bullet proof.
