It is a Pure Power filter. I talked to Vern today and he gave the filter his seal of approval.
Also on a side note, he went on to say there are a bunch of bad paper filters out there now. He would not state brands, but there some with debris that coming out of the paper. Blow in some 15-20 psi air and see if a cloud comes up.
Otherwise he said to keep the purple spring and back it off until the hi rpm pressure is down to 85 to 95#
