So a while back I posted a thread asking how ecore filters hold up in comparison to others. Little did I know I was running a wal mart super tech on my other car for two years with no probs. I just realized that the st is an ecore. Anyhow I love this filter, but so many people on. You tube are quick to say a fram is better. I did however notice that when I went to stock up for my next oil change on my dodge that the. Ecore I bought is about a half inch shorter than the fram. What's up with that?
