Wanted to get every bodies thoughts on Champion labs e-core filters. I'm familiar with the Delco and the Champ lines. They might be the same for all I know. I have no data to back this up but I feel like the open center tube design allows for better less restricted flow. Also I've seen evidence where the adhesive that bonds the media to the end cap seems to bond better to the fiber caps than to metal ones. I'm running a Champ PH820 on one of my Ford trucks now and the ADBV seems to be holding up. I know there are better filters out there but e-core filters seem to be a good balance of quality and cost.
