Unicorn oil filter...

“Champion Labs touts their new “Ecore” design as a major advancement in oil filter technology. In my humble opinion, they are a major advancement in cost savings for Champion. I have no data to back this up, but that’s what fiber end caps and plastic core tubes say to me. I particularly don’t like their “patent pending” bypass valve design, which depends on the stamped leaf spring at the back of the filter to regulate the bypass pressure. One unlucky dent in the back of the can knocks it out of whack, assuming it was correct to begin with”
