I think its worth it, because now i change my oil and full fow filter every 10k miles and my Bypass filter every 20k miles. I am running Amsoil 5W-30 synthetic oil with sampling every 6k miles. I can actually go longer between opil changes but i am more comfortable using this schedule. The key is the oil sampling, this way you are sure you are not hurting anything. If you like changing your oil every 3-5k miles and dont mind the 20 bucks for regular oil plus the Fleetguard filter, then the Amsoil dual bypass is a waste of money, its only worthwhile if you want to extend your intervals. Also, if you are going to get a setup, be sure and get the "CPFF" custom mount, block adaptor and braided lines. The install will be simple with no cutting or fabrication anything, just bolt it in and go. Takes about 45 minutes or less to install with simple hand tools.
