- The lip on the threads of Fram Tough Guard filter makes it a little harder to get threaded since the filter doesn't do a good job of self-centering (easy aiming) like the Mobil 1 does.
.
- The Fram Tough Guard is much taller and it makes it much easier to actually get a grip on the filter when attacking from the top of the radiator support and diving down-in.
